Upscaling the in-situ measured iso/anisohydry of 102 species to 1-degree resolution using GBIF species occurrence and MODIS land cover data

See more details in Li et al 2017 JGR.<b>Data file:</b><br><strong>1. gbif_isohydricity.nc</strong><br>The final upscaled GBIF isohydricity at 1 degree<b>2. MartinezVilalta_IsohydryDatabase_v1.xlsx</b>This is the isohydry database for 102 species from Martínez-Vilalta, J., Poyatos, R., Aguadé, D., Retana, J., Mencuccini, M., 2014.

New Phytol. 204, 105–115. doi:10.1111/nph.12912<b>3. species_occurence_results_2fields.csv.tar.gz<br></b>The 102 species occurrence records extracted from the huge GBIF plant occurrence database (output of <i>extract_species_occurrence_record.py</i>). Each occurrence record comes with latitude and longitude information. <br><b>4. species_grid_2fields.npy.tar.gz</b>The 102 species occurrence record aggregated to 1-degree grid cell.<b>5. MODIS_LC_fraction_multiple_res.mat</b>MODIS land cover fraction (17 classes) at multiple spatial resolutions (0.05, 0.25, 0.5, 1, and 2 degree).<br><b>Code: </b><b>1. extract_species_occurrence_record.py (Python)</b>Extract occurrence records for the 102 species from GBIF data file<b>2. construct_spatial_record_land_cover.py (Python)</b>Calculate grid cell isohydricity value for each PFT group based on species occurrence. It also gives the number of record, and the number of species at the grid cell. The outputs are 3 (variables) x 7 (PFT group)=21 text files. <b>3. func_gbif_isohydricity_map.m (Matlab)</b>It utilize the text files outputed from <i>construct_spatial_record_land_cover.py to </i>calculate grid cell weighed isohydricity value based on the areal fraction of each PFT group.<br>Find more details inYan Li, Kaiyu Guan, Pierre Gentine, Alexandra G.
