WAVeTrends: Trends in Woody and Herbaceous Vegetation

Map of vegetation change in West Africa.

Concurrent woody and herbaceous vegetation changes between the 1982-1991 and 2004-2013 decades of the Sudano-Sahel region of Africa. (A) Map of vegetation change categories. (B) Chart showing the conceptual position and the relative abundance of each category in a 2-D space.

Vegetation change data spanning the West African Sudano-Sahel region is now available.

Boreal Forest Biomass and Soil Metrics at Burned Sites

Map of burned areas across portions of North America.

Field sites, ecoregions, and total area burned (millions of hectares; Mha) in each of the ecoregions in the study domain over time. Grey dotted line in the inset represents the simple linear regression, with red shading for the 95% confidence intervals, of burned area for all ecoregions combined. Analyses were completed using the field site groupings, located within the six ecoregions defined by the EPA Level II Ecoregions of North America.

Burned forest plot data is available from the Arctic-Boreal Vulnerability Experiment (ABoVE).

Active Layer Thickness across Alaska

Map of active layer thickness in Alaska.

Model-simulated 1 km mean active layer thickness (ALT) map from 2001 to 2015. Black dots are locations of circumpolar active layer monitoring (CALM) sites used for comparison of observed ALT to modeled ALT. CALM data are not provided. The areas with ALT greater than 300 cm depth are shown in dark gray.

MODIS and SMAP satellite data were used to derive estimates of active layer thickness and uncertainty.

Soluble Acidic Gases and Aerosols (SAGA) Instrument Data

Instrument: Soluble Acidic Gases and Aerosols (SAGA).

The SAGA installation onboard the DC-8 - AFRC aircraft.

Soluble ion measurements are available from the Atmospheric Tomography Mission (ATom).

Pinyon-Juniper Forest Aboveground Biomass

Map of live aboveground tree biomass for a portion of the Great Basin, USA.

Map of annual live aboveground tree biomass (Mg/ha) for pinyon-juniper forests across a representative portion of the Great Basin of the Western USA for the year 2005 at a spatial resolution of 30 meters.

Maps of live tree biomass in pinyon-juniper forests are available for the years 2000-2016.
