Master and Landsat-8 simultaneous acquisition datacubes for the quantification of directional anisotropy in Thermal Infra-Red domain

‎

This dataset contains datacubes of simultaneous Landsat-8 and Master1 data as listed in table 1. Those pairs have been identified by cross-searching Landsat-8 and Master archive for Master flight tracks with a Landsat-8 overpass during the flight. The dataset has been collected and analysed in the following paper:

Julien Michel, Olivier Hagolle, Simon J Hook, Jean-Louis Roujean, Philippe Gamet. Quantifying Thermal Infra-Red directional anisotropy using Master and Landsat-8 simultaneous acquisitions. 2023. ⟨hal-04073733⟩

Variables of interest are resampled on a common UTM grid at 100m. The resulting datacubes are distributed as netCDF files, and contains the variables listed in table 2. Landsat-8 pixels flagged as cloud and missing pixels are set to NaN.

Landsat-8 products were downloaded from the collection 2 level 2 archive from the EarthExplorer portal2. Master L1B products, containing radiances and viewing angles, as well as L2 products, containing LST and geo-location grids, were requested on the Master website1. Landsat-8 viewing angles have been computed by using a C program publicly available on USGS website3.
