MODIS Inputs for Agroecosystem Modeling

Leaf area index at 30 km resolution for the month of January.

Average leaf area index during January (2003-2010). This figure was created from the data file leaf_stem_area_index_monthly_climatology_2003-2010.nc4.

Vegetation and albedo parameters from MODIS Collection 5 were reprocessed for use in regional agroecosystem-climate models.

Atmospheric Carbon and Trace Gases

Flask air samples from flights in July and August 2016.

Locations of ACT-America flask air samples from flights in July and August 2016.

A new dataset from ACT-America provides data from airborne flasks collected during the Summer 2016 campaign.

ATom Measures Greenhouse Gases and Pollution

Atmospheric Tomography Mission (ATom)

Atmospheric Tomography Mission (ATom) is an Earth Venture Suborbital-2 mission.

NASA's Atmospheric Tomography Mission (ATom) mission conducts atmospheric profiles for systematic, global-scale sampling of the atmosphere.

Phenology Derived from Landsat

Map of the 75 selected Landsat sidelap regions

Spring and Autumn phenology was calculated for 75 Landsat sidelap regions. From Melaas et al., 2018.

A 30 year timeseries of spring and autumn phenology across North American forests was derived from Landsat imagery.

Visualize Airborne Data

The Airborne Data Visualizer showing CO2 and CH4 concentrations

Screenshot of the Airborne Data Visualizer showing a flight from the ACT-America campaign. CO2 and CH4 concentrations are shown from the B-200 aircraft on July 11, 2016.

A new tool allows users to explore airborne data from multiple missions.
