        ## About
        
        JAWS is a scientiﬁc software workﬂow to ingest Level 2 (L2) data in the multiple formats now distributed, harmonize it into a common format, and deliver value-added Level 3 (L3) output suitable for distribution by the network operator, analysis by the researcher, and curation by the data center. NASA has funded JAWS (project [summary](http://dust.ess.uci.edu/prp/prp_aist/prp_aist_smr.pdf)) from 20171001&ndash;20190930.
        
        Automated Weather Station (AWS) and AWS-like networks are the primary source of surface-level meteorological data in remote polar regions. These networks have developed organically and independently, and deliver data to researchers in idiosyncratic ASCII formats that hinder automated processing and intercomparison among networks. Moreover, station tilt causes signiﬁcant biases in polar AWS measurements of radiation and wind direction. Researchers, network operators, and data centers would beneﬁt from AWS-like data in a common format, amenable to automated analysis, and adjusted for known biases.
        
        The immediate target recipient elements are polar AWS network managers, users, and data distributors. L2 borehole data suffers from similar interoperability issues, as does non-polar AWS data. Hence our L3 format will be extensible to global AWS and permafrost networks. JAWS will increase *in situ* data accessibility and utility, and enable new derived products.
        
        ## Overview
        
        ### JAWS consists of:
        
        #### 1) Standardization
        
        Convert L2 data (usually ASCII tables) into a netCDF-based L3 format compliant with metadata conventions (Climate-Forecast and ACDD) that promote automated discovery and analysis. 
        
        #### 2) Adjustment
        
        Include value-added L3 features like the Retrospective, Iterative, Geometry-Based (RIGB) tilt angle and direction corrections, solar zenith angle, standardized quality flags, GPS-derived ice velocity, and turbulent fluxes.
        
        #### 3) API
        
        Provide a scriptable API to extend the initial L2-to-L3 conversion to newer AWS-like networks and instruments.

        ## Installation
        
        #### Requirements:
         * Python 2.7, 3.6, or 3.7 (as of JAWS version 0.7)
        
        #### Installing pre-built binaries with conda (Linux, Mac OSX, and Windows)
        
        By far the simplest and recommended way to install `JAWS` is using [conda](https://conda.io/docs/) (which is the wonderful package manager that comes with [Anaconda](https://conda.io/docs/user-guide/install/index.html) or [Miniconda](https://conda.io/miniconda.html) distribution).
        
        You can install `JAWS` and all its dependencies with:
        ``` html
        $ conda install -c conda-forge jaws
        ```
        
        #### Installing from source
        
        If you do not use conda, you can install `JAWS` from source with:
        ``` html
        $ pip install jaws
        ```
        (which will download the latest stable release from the [PyPI repository](https://pypi.org/) and trigger the build process.)
        
        pip defaults to installing Python packages to a system directory (such as /usr/local/lib/python2.7). This requires root access.
        
        If you don't have root/administrative access, you can install `JAWS` using:
        ``` html
        $ pip install jaws --user
        ```
        `--user` makes pip install packages in your home directory instead, which doesn't require any special privileges.
        
        #### Update
        
        Users should periodically update JAWS to the latest version using:
        ```html
        $ conda update -c conda-forge jaws
        ```
        or
        
        ```html
        $ pip install jaws --upgrade
        ```
        
        <!--
        ___
        ## Obtaining JAWS
        
        First-time users can execute this to copy JAWS to their local machines:
        
        ``` html
        $ git clone https://github.com/jaws/jaws.git
        ```
        
        Those with GitHub accounts who wish to contribute to JAWS should clone via SSH instead:
        
        ``` html
        $ git clone git@github.com:/jaws/jaws.git
        ```
        
        Users should periodically update their local repositories to the current version:
        
        ``` html
        $ git pull
        ```
        
        ### Pre-requisites 
        
        JAWS works with any Python distribution, and especially well with Anaconda and [Miniconda](https://conda.io/miniconda.html)

        ___
        ## Example
        JAWS is a command-line tool. Linux/Unix users can run JAWS from terminal and Windows users from Anaconda Prompt. 
        
        The current version can translate L2 ASCII data from the following networks to netCDF format: 
        * Antarctic Automatic Weather Stations (AAWS): Sample raw file can be downloaded from [here](http://jaws.ess.uci.edu/jaws/sample_data/AAWS_AGO-4_20161130.txt). Right click on the link and select "Save link as".
        * Greenland Climate Network (GCNet): Sample raw file can be downloaded from [here](http://jaws.ess.uci.edu/jaws/sample_data/GCNet_Summit_20120817.txt)
        * Institute for Marine and Atmospheric Research (IMAU): Sample raw file for Antarctic stations can be downloaded from [here](http://jaws.ess.uci.edu/jaws/sample_data/ant_aws17IMAU_20150101.txt) and for Greenland stations can be downloaded from [here](http://jaws.ess.uci.edu/jaws/sample_data/grl_aws05IMAU_20151008.txt)
        * Programme for Monitoring of the Greenland Ice Sheet (PROMICE): Sample raw file can be downloaded from [here](http://jaws.ess.uci.edu/jaws/sample_data/PROMICE_EGP_20160503.txt)
        * Scientific Committee on Antarctic Research (SCAR): Sample raw file can be downloaded from [here](http://jaws.ess.uci.edu/jaws/sample_data/SCAR_Sofiab_aws.dat)
        * The Polar Earth Observing Network (POLENET): Sample raw file can be downloaded from [here](http://jaws.ess.uci.edu/jaws/sample_data/polenet_FoynPoint_20100208.dat)
        * National Snow & Ice Data Center (NSIDC): Sample raw file can be downloaded from [here](http://jaws.ess.uci.edu/jaws/sample_data/NSIDC_890010_19730101_19730901.dat)
        
        ```
        Note:
        
        For PROMICE, input file name must contain station name. e.g. 'PROMICE_KAN-B.txt' or 'KAN-B.txt' or 'Kangerlussuaq-B_abc.txt', etc.
        
        For IMAU, input file name must start with network type(i.e. 'ant' or 'grl'), followed by a underscore and then station number. e.g. 'ant_aws01.txt' or 'ant_aws15_123.txt' or 'grl_aws21abc.txt', etc.
        
        For SCAR, input file name must end with '_aws.dat'
        
        For POLENET, input file name must start with 'polenet_'
        ```
        The user provides the input file path. By default, the output file will be stored within the current directory with same name as of input file (e.g. PROMICE_EGP_20160501.nc). The user can optionally give their own output path/name. Execute this to get output file in current directory:
        
        ``` html
        $ jaws ~/Downloads/PROMICE_EGP_20160501.txt
        ```
        
        or by specifying longer paths, and with options:
        
        ``` html
        $ jaws -4 -o ~/Desktop/PROMICE_EGP_20160501.nc ~/Downloads/PROMICE_EGP_20160501.txt
        $ jaws -4 -o ~/Desktop/GCNet_Summit_20140601.nc ~/Downloads/GCNet_Summit_20140601.txt
        $ jaws -4 -o ~/Desktop/AAWS_AGO-4_20161130.nc ~/Downloads/AAWS_AGO-4_20161130.txt
        ```
        
        where the argument to the optional `-o` is the user-defined output filename
        
        A list of all options can be found in [here](docs/source/Arguments.md).
        
        #### __RIGB__
        
        Download sample data from [here](http://jaws.ess.uci.edu/jaws/sample_data/gcnet_summit_20120817.txt)
        
        To run RIGB:
        
        ``` html
        $ jaws ~/Downloads/gcnet_summit_20120817.txt --rigb
        ```
        
        RIGB uses [climlab](https://github.com/brian-rose/climlab) package to simulate clear-sky radiation.
        
        #### Value Added Information
        
        In addition to input variables, `JAWS` provides following variables in output netCDF file to make data more useful:
        
         * time (seconds since 1970-01-01 00:00:00)
         * time_bounds
         * sza (solar zenith angle)
         * latitude
         * longitude
         * ice_gps_velocity_x, ice_gps_velocity_y, ice_gps_velocity_total (For stations that archive GPS position)
         * year, month, day, hour
         * adjusted_fsds (corrected downwelling shortwave flux)
        
        #### Analysis Example
        
        Currently, the **input file** for analysis should be in **netCDF format**. So, first the raw ASCII files should be converted to 
        netCDF using previous steps. We are working to make it accept ASCII files as input.
        
        In the following examples we have used GCNet station at Summit, if you are using a separate network, you need to change 
        the variable name accordingly.
        
        JAWS has ability to analyse the data in multiple ways such as:
        
        i. **Diurnal**:
        
        JAWS can be used to plot monthly diurnal cycle to see hourly changes for any variable throughout the month. 
        The user needs to provide input file path, variable name (on which analysis needs to be done) and 
        analysis type (i.e. diurnal, monthly, annual or seasonal). The argument for analysis is `-a, --anl or --analysis` and
        variable name is `-v, --var or --variable`.
        
        We will take two examples here:
        
        * ***Case 1***: The input file contains only 1-day data. We will consider the file converted previously i.e.
         [GCNet_Summit_20120817.nc](http://jaws.ess.uci.edu/jaws/sample_data/converted/GCNet_Summit_20120817.nc)
        
            Use the following command to see how ***temperature*** varies throughout the day:
            ```
            $ jaws -a diurnal -v ta_tc1 GCNet_Summit_20120817.nc
            ```
        
            ![](http://jaws.ess.uci.edu/jaws/img/diurnal_summit_20120817.png)
        
        * ***Case 2***: We will be using multi-year data from GCNet-Summit. We don't have permission to host this data.
        
            Since, there are many years and months in this file, we need to provide for which year and month 
            we want to do the analysis. The argument for year is `-y, --anl_yr or --analysis_year` and 
            month is `-m, --anl_mth or --analysis_month`.
         
            If the input file contains data for only single year, then the user doesn't  need to provide the '-y' argument. 
            Similar is the case for '-m' (month) argument.
        
            We will do the analysis for May-2002 at GCNet_Summit:
            ```
            $ jaws -a diurnal -v ta_tc1 -y 2002 -m 5 gcnet_summit.nc
            ```
            
            ![](http://jaws.ess.uci.edu/jaws/img/diurnal.png)
            
            The blue error bar shows standard deviation for that hour across the month.
        
        ```
        Important: This same file from Case 2 will be used for next three analysis because we need at-least monthly, yearly and 
        multi-yearly data respectively for them.
        ```
        
        ii. **Monthly**:
        
        In this analysis, we can analyze avg, max and min values for each day of a month for any variable
        
        This time we will do it for ***temperature*** from different sensor for Feb-2013 as following:
        
        ```
        $ jaws --anl monthly --var ta_cs1 --anl_yr 2013 --anl_mth 2 gcnet_summit.nc
        ```
        
        ![monthly](http://jaws.ess.uci.edu/jaws/img/monthly.png)
        
        iii. **Annual**:
        
        To plot an annual cycle with daily mean, max and min:
        
        ```
        $ jaws --analysis annual --variable ta_tc1 --analysis_year 2016 gcnet_summit.nc
        ```
        
        Note: Since it is annual plot, user shouldn't provide the '-m' argument
        
        ![annual](http://jaws.ess.uci.edu/jaws/img/annual.png)
        
        iv. **Seasonal**
        
        Climatological seasonal cycle showing variation for each month through multiple years:
        
        ```
        $ jaws -a seasonal -v ta_tc1 gcnet_summit.nc
        ```
        
        Note: Since it is seasonal plot, user shouldn't provide both '-y', '-m' argument.
