Data for "Snow Effective Grain Size and Albedo Patterns Mapped from UAV Hyperspectral Imaging to Assess Landsat 9 OLI Pixel Variability: A Case Study from Senator Beck Basin, Colorado"

Uploaded here the code and data repository for "UAV hyperspectral imaging for multi-scale assessment of Landsat 9 effective snow grain size and albedo" published in Frontiers of Remote Sensing (2022/2023). <br> Description of the data and scripts that are located in the repository. <br> field_spectrometer This folder contains two matlab data files. 1) "ASD spectra" contains 34 ASD field spectrometer reflectance measurements that are resampled to the Resonon NIR-HSI wavelengths. 2) "ASD_gps_coordinates" contains UTM coordinates for for the 34 ASD field spectrometer meassurments from (1). Example: ASD_spec(:,1) is located at ASD_coords(1,:). <br> landsat_retrievals This folder contains Landsat 9 grain size and albedo retrievals, and corresponding statistical runs as geotiffs. <br> nir_hsi_mosaics (1)This folder contains the mosaiced reflectance datacube pre- and post-vicarious calibration. (2) The grain size retrieval for the post-vicariously calibrated reflectance mosaic (3) The raw radiance mosaic (used for georeference in the spatial comparison script) <br> matlab_code albedo_landsat_visualization contains the proram that performs the spatial analysis between ASD, UAV-HSI, and Landsat. The UAV-HSI albedo calculation is also performed in this program. <br> <br> grain_size_retreival contains the grain size retrieval algroithms for ASD and NIR-HSI and the corresponding SNICAR lookup table for a 41deg zenith angle. <br> matlab functions folder should be in the path and are called in the codes provdied. <br> <br> THE SOFTWARE IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
