30 Year Landsat Time Series

An effort is underway to compile and make available a collection of Landsat scenes for each LTER site. The catalog will span from 1982 through 2011, and will provide 30 years of standardized historical data. Raw images will be available, as well as atmospherically corrected images. The corrected images will have two options: top of atmosphere reflectance, and surface reflectance. Read More…

NASA's Airborne Visible InfraRed Imaging Spectrometer (AVIRIS)
Over the past 20 years, the AVIRIS instrument has acquired data throughout the Northeast, with an emphasis on collections over Hubbard Brook and the Harvard Forest LTER sites. Among the products from these data, are estimates of foliar chemistry, productivity and surface albedo.

Using LiDAR to Map Bird Habitat

Researchers use the Laser Vegetation Imaging Sensor (LVIS) in combination with Landsat data to identify areas of preferred habitat for the Black-throated Blue Warbler within the Hubbard Brook forest. Read about their work here and here.

NH EPSCoR Hyperspectral Data (SpecTIR)

In 2012, Hyperspectral data were collected from a commercial vendor (SpecTIR), covering three watershed in NH (Hubbard Brook, Bartlett Experimental Forest, and Lamprey). These watershed include areas of managed and  unmanaged forest, and suburban development. Read More…

Passive Microwave Detection of Snowmelt and Runoff

Snow melt provides the dominant hydrologic signal for many watersheds across the globe. Spring melt is a major transition period that is demarked by significant changes in the land and aquatic ecosystems. This study makes use of the long term Hubbard Brook snow record and a 30-year near-daily record of satellite microwave observations to study the variability of snow water and snow density in time and space.
