Global map of daily mean Solar Induced Fluorescence (SIF) for July 2010 at 0.05 degree resolution. The USA's Corn Belt (insert) showed the largest SIF emission during the growing Season (Image Credit: Jiaming Wen 2022).
Datasets from the Solar Induced Fluorescence Earth Science Data Record (SIF-ESDR) have been integrated into ORNL DAAC subsetting tools, TDS with learning resources available, and Earthdata Cloud.
Annual timeseries of daily cross-validation mean absolute error (MAE), averaged over all station days for each year, comparing results for Daymet V4 and Daymet V3. (a) MAE for estimation of daily maximum temperature. (b) MAE for estimation of daily total precipitation. Image from Thornton et al. 2021.
A recent publication by Thornton et. al., 2021, Gridded daily weather data for North America with comprehensive uncertainty quantification, details improvements to the Daymet V4 Model.
Example subset of aboveground biomass density (AGBD; Mg ha-1) predictions from the GEDI Level-4A footprint version 2.1 product over Northern California, USA, spanning April to July 2019. GEDI footprints are spaced 60m along track and 600m across-track.
GEDI L4A Footprint Level Aboveground Biomass Density, Version 1 released.
Color infrared image of Big Trail Lake in the Goldstream Creek Valley north of Fairbanks, Alaska. Ground control points (yellow triangles) surround the lake. Image was produced from NIR (red), red (green), and green (blue).
Very high resolution multispectral reflectance imagery, normalized difference vegetation index (NDVI), and digital surface and terrain models for a 0.5 km2 area surrounding Big Trail Lake (BTL) with soil collar locations for measuring carbon flux.
Location of 15 lakes surveyed for methane ebullition hotspots (green points) north of Fairbanks, AK, on October 8, 2014. Inset shows detail of Eagle Lake with locations of 43 hotspots (red points) detected by openings in lake ice.
