Carbon Sequestration Potential for Maryland

Maximum forest aboveground biomass

Carbon sequestration potential within the state of Maryland, defined as 95% of maximum forest aboveground biomass (Mg/ha), simulated after 500 years of succession.

A new dataset maps the aboveground biomass of Maryland's forests and estimates their potential for future carbon sequestration.

Daymet 2018 Data Now Available

Daymet provides high-resolution surface meteorology data for North America.

Daymet provides high-resolution surface meteorology data for North America. The figure shows annual data for the year 2018; Left: Mean maximum daily temperature, Middle: Total precipitation, Right: Mean minimum daily temperature. Daymet data is archived and distributed by the ORNL DAAC.

Daymet weather and climate data for North America are now available for the years 1980 - 2018.

Merged Data from the Atmospheric Tomography Mission

ATom flights

Generalized overview of ATom flights. During each of the four campaigns, ATom flights originated from California, flew south over the Pacific Ocean, then north to the western Arctic, southwest to New Zealand, east to Chile and the Atlantic Ocean, north to Greenland, and returned to California across North America. During flights, the aircraft continuously profiled the atmosphere from 0.2 to 12 km altitude.

The Atmospheric Tomography Mission (ATom) has released multi-instrument merged data from all four flight campaigns spanning from 2016 - 2018.

MODIS Collection 6 Phenology and Other Updates

MODIS pixel quality for Paradise, CA

Periodic fires near Paradise, California (in 2001, 2008, and 2018) observed from MODIS as recorded in the newly released MCD64A1 product: MODIS/Terra and Aqua Burned Area Monthly L3.

Several updates are now available for MODIS Land Products, including the addition of the Collection 6 phenology product.

ACT-America L2 Flask Data Updated

Flask air sample locations

Locations of ACT-America flask air samples from all flight data available to date.

Atmospheric trace gas concentrations collected by the ACT-America project have been updated to include Fall 2017 and Spring 2018 flights.

AirSWOT Ka-band Radar from ABoVE

AirSWOT radar products from ABoVE

Example of AirSWOT radar products in ABoVE Projection at 3.6 m resolution, for a flight over the ABoVE C grid Ch065v034. Left: Shape for backscatter image. Middle: Backscatter magnitude shows bright reflection in the near range and no returns, yielding regions of no data, in the far range. Right: Derived elevation product.

The ABoVE project has released data from AirSWOT flights in Summer 2017 collected over Alaska and Canada.

Greenness Trends for Alaska and Canada

Landsat NDVI times series for 1984-2012

NDVI trends derived from 30 m Landsat NDVI times series for 1984-2012 across Canada and Alaska.

A new dataset from NASA's ABoVE campaign provides trends in NDVI over the Landsat era.

High-resolution reflectance data from the Arctic

Soil Adjusted Vegetation Index

Soil Adjusted Vegetation Index (SAVI) for a site on the Seward Peninsula, Alaska collected on August 14, 2018. SAVI is similar to NDVI, but it suppresses the effects of soil pixels and it uses a canopy background adjustment factor. The reflectance data used to calculate SAVI was collected by the AVIRIS-NG instrument on a flight over the Seward Peninsula, Alaska, on August 14, 2018.

New AVIRIS-NG data from the 2018 ABoVE airborne campaign and an accompanying data processing tutorial are now available.

Introduction to Geospatial Analysis in R

Forest disturbance by fire and insect infestation

The webinar featured data on the locations of forest disturbance by fire (red) and insect infestation (yellow) across northwestern USA between 2006 and 2010.

The recording of our NASA Earthdata webinar on "Introduction to Geospatial Analysis in R" is now available.
