Spatial distribution of eight wolf study populations used in an assessment (from 2000-2017) of denning phenology in response to climate signals. The base map shows the day of the year representing the NDVI-derived start of the growing season in 2010.
Eighteen years of annual gray wolf (Canis lupus) denning spatial information and timing across within the NASA ABoVE Core Domain recently published.
DEM of the Global Change Research Wetland (GCReW) site generated using the LEAN (LiDAR Elevation Correction with NDVI) method. LEAN uses ground measurements of elevation and NDVI in a multivariate linear regression model to estimate vertical bias.
Four digital elevation models (DEMs) at 1-m resolution and 2106 model performance metrics for the GCReW site, Maryland, USA are now available.
Sites in Version 2 of the Permafrost Dynamics Observatory Project product. Green = data delivered in Version 2. Red = not delivered in Version 2 but will be delivered in future version. Yellow = not processed due to only L-band data being available.
Estimates of seasonal subsidence, ALT, vertical soil moisture profile, and uncertainties at a 30-m resolution for 28 sites across the ABoVE domain are now available.
Riverine N2O emission estimates from headwater streams (a, c, and e) and high-order rivers (b, d, and f) for the 1900s, 1960s, and 2000s. The right panel shows the latitudinal distribution of riverine N2O emissions with the uncertainty range as the standard deviation (shaded areas).
Modeled estimates of annual NO2 emissions for two sets of global rivers and streams covering years 1900-2016 available.
