Training dataset for land surface temperature guided super-resolution

This datset contains the training, validation and evaluation sets for training a guided super-resolution alogirthm in order to downscale AVHRR data to the spatial resolution of the MODIS LST dataset.

The dataset is splited in three distinct folders:

• Train
• Val
• Eval

All data were extracted from the ESA CCI Climate toolbox (https://climate.esa.int/en/data/toolbox/) and saved as separate GeoTiff files. The LST data were extracted from the ESA LST CCI products 'MODIS-AQUA' and 'IRCDR'.

In addition auxiliary data such as land cover, digital elevation model and vegetation height data used as a guide for the guided super-resolution are provided. The following datasets were used to create the guide:

• The Copernicus digital elevation model (DEM) GLO-90, upscaled to 0.01° spatial resolution (https://doi.org/10.5270/ESA-c5d3d65).
• ESA CCI Land Cover for the year 2005 (https://www.esa-landcover-cci.org). The spatial resolution of the original data was upscaled to 0.01° to match the MODIS LST dataset. This upscaling was achieved by selecting the most frequent land cover class within each upscaled pixel, ensuring consistency with the original land cover distribution.
• A high-resolution canopy height model (https://langnico.github.io/globalcanopyheight/).

All data has been aligned to match the extact MODIS gridded product at 1km spatial resolution.

More information can be found in the dedicated paper (Preprint).
