OpenET - v0.7.0

Removed Tmax dependency and switched from computing Tcorr to computing Tcold directly (i.e. Tmax * Tcorr).

OpenET - v0.6.0

Major update to the Tcorr FANO calculation. Landcover masking was introduced allowing for areas that are hot-dry regularly (non-ag, non-wetlands, non-grasslands) to be modeled with tcorr from FANO at 240m resolution.

Agriculture, wetlands and grasslands are modeled using 240m resolution Tcorr as well, but only if the average NDVI within 240 meters is 0.4 or above. Otherwise, a 5km FANO Tcorr is used as a fallback, which only makes use of pixels that meet the NDVI threshold greater than 0.4.

This keeps areas that are low NDVI AND low LST out of FANO in areas that have a propensity to have wet soils (ag, grassland, wetland).

OpenET - v0.4.0

Removed numerous deprecated functions, tools, methods, and options. This includes the Tcorr, dT, and Tmax source keywords, as well as the dT clamping and reflectance_type options.

The LST correction will now be applied by default unless "c2_lst_correct" is set to False in the Image initialization.

OpenET - v0.3.2

Added support for explicitly setting the data source used for the ET fraction alfalfa to grass reference conversion using the et_fraction_grass_source parameter. The default is the NLDAS hourly image collection NASA/NLDAS/FORA0125_H002. The source parameter is currently optional, but will become a required parameter in a later version (if et_fraction_type='grass').

OpenET - Landsat Collection 2 LST Correction

Added support for applying the Landsat Collection 2 LST correction in openet-core (added in version 0.1.1).

The correction can be applied by setting the "c2_lst_correct" keyword argument to True in the Image class initialization. The default value is currently set to False, but this may be changed in a future version.
