Package to perform Wind inversion from GRD Level-1 SAR images

-   Free software: MIT license

-   Documentation: https://cerweb.ifremer.fr/datarmor/doc_sphinx/grdwindinversion/index.html.

## Usage

```python

   SAR_L1-to-L2_wind_processor -h

   usage: SAR_L1-to-L2_wind_processor [-h] --input_file INPUT_FILE [--config_file CONFIG_FILE] --outputdir OUTPUTDIR [--verbose] [--overwrite]

   Perform inversion from S1(L1-GRD) SAFE, L1-RCM, L1-RS2 ; using xsar/xsarsea tools

   options:

     -h, --help            show this help message and exit

     --input_file INPUT_FILE

                           input file path

     --config_file CONFIG_FILE

                           config file path [if not provided will take config file based on input file]

     --outputdir OUTPUTDIR

     --verbose

     --overwrite           overwrite existing .nc files [default is False]

```

## Features

This Python library (based on `xarray`) allows to perform wind inversion from level-1 GRD (projected magnitude image).

Mission supported:

-   Sentinel-1

-   RCM

-   RadarSat-2
