A new global land parameter database derived from AMSR-E multi-frequency microwave remote sensing released

A new global land parameter database derived from AMSR-E multi-frequency microwave remote sensing released

This database contains a set of derived parameters including screen-height max/min air temperatures, vegetation optical depth, fractional open water cover, freeze/thaw status, atmospheric water vapor content and surface soil moisture. The data are posted to a 25-km global EASE-grid projection.

Diagnosis and prognosis of changes in lake and wetland extent on the regional carbon balance of northern Eurasia

Diagnosis and prognosis of changes in lake and wetland extent on the regional carbon balance of northern Eurasia

The goal of the project is to investigate the relationship between changes in lake and wetland extent and the regional carbon balance in northern Eurasia over the last half-century, and to predict the likely impacts of changes in lake and wetland extent on the carbon balance in this region over the next century. Our approach is to develop a historical time series of observed lake and wetland extent via a combination of high resolution, slow-repeat-cycle SAR data (primarily from ALOS/PALSAR) and low-resolution, fast-repeat-cycle passive microwave data (primarily from AMSR-E).

Quantifying changes in northern high latitude ecosystems and associated feedbacks to the climate system

Quantifying changes in northern high latitude ecosystems and associated feedbacks to the climate system

The primary focus of this NASA supported research project is to examine the tradeoffs between carbon and energy fluxes in two boreal forest study regions (Interior Alaska and Cherskii Russia) across three different periods of post-fire succession: (1) immediately following fire (years 1-6 after fire), (2) at intermediate stand ages (20-40 years after fire), (3) in older stands (more than 60 years after fire).

Urban growth impacts on surface hydrology in Mid-Atlantic and New England watersheds

Urban growth impacts on surface hydrology in Mid-Atlantic and New England watersheds

This project was focused on the use of land cover products and spatial predictive land use modeling to inform hydrologic models and assess the risk of flooding and resource land losses associated with future development across watersheds of the mid-Atlantic and southern New England regions.
