Description

This data set provides atmospheric carbon dioxide (CO2), methane (CH4), carbon monoxide (CO), ozone (O3), and water vapor (H2O) concentrations from airborne campaigns over the Alaskan and Canadian arctic for the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE). These data are merged and gap-filled outputs from two different cavity ring-down spectrometers (CRDS; Picarro Inc.) flown aboard the CARVE aircraft and are presented at 5-second intervals throughout each flight. Aircraft latitude, longitude, and altitude are also provided. Flight campaigns took place from 2012 to 2015 between the months of March and November to enable investigation of both seasonal and inter-annual variability in atmospheric gas content. The measurements included in this data set are crucial for understanding changes in Arctic carbon cycling and the potential threats posed by thawing of Arctic permafrost.

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.
