ORNL DAAC Hopes to See You at AGU

AGU 100 Advancing Earth and Space Science

See you at AGU, December 9-13 in San Francisco.

Several ORNL DAAC staff members will be attending the American Geophysical Union Meeting December 9-13, 2019, in San Fransisco, CA.

Seasonality of Photosynthetic Performance

SIF for CLM Simulation Year 2010

Simulated and observed seasonal patterns of canopy SIF (740 nm) for (a, c) absolute SIF and (b, d) normalized canopy SIF for CLM simulation year 2010. Both a satellite SIF product (GOME-2) and the PhotoSpec measurements are included for comparison.

Three related datasets from the Carbon Monitoring System (CMS) program describe year-round photosynthetic activity in a conifer forest.

Atmospheric Oxygen and CO2 Concentrations

AO2 Measurements

Example cross-sections of CO2, O2, and APO (O2 + 1.1 * CO2) measured by AO2 (interpolated flight track data) and the Medusa flask sampler (filled circles) during the Pacific southbound flights of ATom-4 in April and May 2018.

Data collected by the Airborne Oxygen Instrument (AO2) during the Atmospheric Tomography (ATom) airborne campaigns are now available.

Pre-Fire Ecosystem Classifications in Burned Area

Great Slave Lake

Ecosystem map for the Great Slave Lake area, Northwest Territories, Canada, for the period 1997-2011.

ABoVE researchers compiled a map of ecosystem states prior to the 2014 & 2015 fires in the Northwest Territories, Canada.
