Total Column Gases from CARVE Airborne FTS

Total column CH4 retrievals from a CARVE flight on May 23, 2012, flying north from Fairbanks over the North Slope to Barrow.

CARVE: L1 Spectral Radiances from Airborne FTS, Alaska, 2012-2015
CARVE: L2 Column Gas and Uncertainty from Airborne FTS, Alaska, 2012-2015

Total vertical column O2, CO2, CH4, CO, and H2O data, as well as dry-air columns of CO2, CH4, CO, and H2O from airborne campaigns over the Alaskan and Canadian Arctic for the Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) have been released. The data represent the Level 2 Quick Retrieval (L2QR) data product collected using the CARVE Fourier Transform Spectrometer (FTS). 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. Level 1 raw spectral radiance data from the Fourier Transform Spectrometer (FTS) is also available. These measurements are crucial for understanding changes in Arctic carbon cycling and the potential threats posed by thawing of Arctic permafrost.
