goescalibration

A python library that allow to automate the calibration of the GOES Images.

Requirements

If you want to use this library on any GNU/Linux or OSX system you just need to execute:

$ pip install goescalibration

If you want to improve this library, you should download the github repository and execute:

$ make virtualenv deploy

On Ubuntu Desktop there are some other libraries not installed by default (zlibc curl libssl0.9.8 libbz2-dev libxslt-dev libxml-dev) which may need to be installed to use these library. Use the next command to automate the installation of the additional C libraries:

$ make ubuntu virtualenv deploy

Testing

To test all the project you should use the command:

$ make test

Example

There are 3 methods to obtain the calibration parameters:

1. calibration
2. calibration_to
3. calibrate

The calibration method accepts 2 parameters the satellite and a datetime object:

    from goescalibration import instrument 
    from datetime import datetime

    params = instrument.calibration('goes13', datetime(2014, 11, 10))

Next, the calibration_to method needs a standard NOAA CLASS netcdf filename to parse:

    from goescalibration import instrument 
    from datetime import datetime

    params = instrument.calibration_to('data/goes13.2014.124.123422.BAND_01.nc')

Last, the calibrate method needs a standard NOAA CLASS netcdf filename to save the variables:

    from goescalibration import instrument 
    from datetime import datetime
    from netcdf import netcdf as nc

    instrument.calibrate('data/goes13.2014.124.123422.BAND_01.nc')
    with nc.loader('data/goes13.2014.124.123422.BAND_01.nc') as root:
        print nc.getvar(root, 'postlaunch')[:]
