Description

This data set provides 3-hourly estimates of gross ecosystem CO2 exchange (GEE) and respiration (autotrophic and heterotrophic) for the state of Alaska from 2012 to 2014. The data were generated using the Polar Vegetation Photosynthesis and Respiration Model (PolarVPRM) and are provided at ~ 1 km2 [1/4-degree (longitude) by 1/6-degree (latitude)] pixel resolution. The PolarVPRM produces high-frequency estimates of GEE of CO2 for North American biomes from remotely-sensed data sets. For Alaska, the model used meteorological inputs from the North American regional re-analysis (NARR) and inputs of fractional snow cover and land surface water index (LSWI) from the Moderate Resolution Imaging Spectroradiometer (MODIS). Land surface greenness was factored into the model from three sources: 1) Enhanced Vegetation Index (EVI) from MODIS; 2) Solar Induced Florescence (SIF) from the Orbiting Carbon Observatory 2 (OCO-2); and 3) SIF from the Global Ozone Monitoring Experiment 2 (GOME-2). Three independent estimates of GEE are included in the data set, one for each source of greenness observations.

Project

Carbon in Arctic Reservoirs Vulnerability Experiment: The Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) is a NASA Earth System Science Pathfinder Mission. From 2011 to 2015, CARVE collected airborne measurements of atmospheric carbon dioxide, methane, and carbon monoxide and relevant land surface parameters in the Alaskan Arctic. Continuous ground-based measurements provide temporal and regional context as well as calibration for CARVE airborne measurements. CARVE provides an integrated set of greenhouse gas data that provides experimental insights into Arctic carbon cycling.
