Calculates and compares the radiance of a thermal LANSAT scene to the "ground truthradiance as measured by a NOAA buoy.

Project description

Calculates and compares the radiance of a thermal LANSAT scene to the "ground truth"
radiance as measured by a NOAA buoy. Based on work by Frank Padula and Monica Cook.

If you want to use this code, you should have a basic knowledge of python and/or basic coding.
No warranty. Use it on armstrong or related servers for best results. Developed on Fedora x64 by Nathan Dileas.
Copyright RIT 2015-2016

OVERVIEW:
This code essentially has two funtions: calculating the radiance from the landsat image
provided, and calculating the corresponding ground truth radiance from outside data,
atmospheric (NARR or MERRA-2), NOAA buoy data, and MODTRAN. Use the file controller.py as
a convinient command line interface or the underying class itself, in bin/BuoyCalib.py.

NARR:
This is the primary atmospheric data source for the project. Height, Temperature,
Humidity as a funtion of Pressure. NCEP Reanalysis data provided by the NOAA/OAR/ESRL
PSD, Boulder, Colorado, USA, from their Web site at http://www.esrl.noaa.gov/psd/

Website: http://www.esrl.noaa.gov/psd/data/gridded/data.narr.html
FTP: ftp://ftp.cdc.noaa.gov/Datasets/NARR/pressure/
MERRA-2:
This is the secondary atmospheric data source for the project. Height, Temperature,
Humidity as a funtion of Pressure. It was instituted as a result of the NARR dataset
not being up to date. Until late 2016, the NARR archive only reaches to late 2014.

NOAA:
This is the only source of water temperature information for the project.

USAGE:
./buoy-calib, in this directory. Use the -h option for more information
on flags and options that are available.

./buoy-calib [options] <Landsat_ID>

Examples:
./buoy-calib -i LC80130332013145LGN00 : Output an image with the location
of the buoy and narr points drawn on it
./buoy-calib -m LE70160382012268EDC00 : Use MERRA data instaed of NARR
./buoy-calib -b 44009 LT50410372011048PAC01 : use a specific NOAA buoy
./buoy-calib -imvr LC80130332013145LGN00 : Output an image, verbose, reprocesss, with MERRA data
./buoy-calib LE70160382012268EDC00 LC80130332013145LGN00 : process more than one scene


The Landsat ID can be any valid ID from landsat 5 or 8 with a level 1 product available.
If there is an error, check earth explorer first. It is frequently down for maitenance.
In future, there may be a tool included with this package to check if the ID is valid before
trying to download. Stay tuned.

TOOLS:
tools/to_csv.py: used to compile results quickly and easily.
tools/generate_atmo_figure.py : generate a figure using information from a already processed scene.
test/functional/run_all_scenes.bash: run a batch of scenes. Move it to this directory before use.
