Interannual variation in gross primary productivity (GPP) across conterminous United States. Map of annual mean GPP for 2018 (a) and 2019 (b). Map of the difference in annual mean GPP between 2019 and 2018 (c) wherein red indicates higher GPP in 2019 and blue indicates higher GPP in 2018. The inset in the bottom left corner shows a time series of the average GPP across CONUS for 2018 and 2019.
Estimates of GPP for CONUS from 2018-02-15 to 2021-10-15, based on measurements of solar-induced chlorophyll fluorescence from TROPOMI on the Sentinel-5P satellite platform.
The CARAFE payload. (a) The NASA C-23 Sherpa. (b) A view inside the cabin with all instruments installed. (c) The angle-of-attack (upper) and total air temperature (lower) probes. (d) The DLH window plate (upper left) and fairing-mounted target (lower right). (e) GHG inlet. (f) Flux leg flight tracks for both campaigns.
Airborne EC fluxes of carbon dioxide, methane, sensible heat, & latent heat collected during the NASA CARAFE 2016 and 2017 campaigns.
Casual agents of disturbance for the year 2006 in the ABoVE domain for tile BH19V15 (A) with the Tasseled Cap change (dTC) image in the same year for the same region (B). In the dTC image, Band_1 is change in brightness; Band_2 is change in greenness; Band_3 is change in wetness. The pixel resolution is 30 meters.
Spatial data on disturbance agents of fire, insects, and logging in the ABoVE core domain at an annual time step from 1987-2012 and 30 m resolution.
