Hubbard Brook Experimental Forest: Hyperspectral Reflectance Imagery, March 2013

General Information
Data Package:
Local Identifier:knb-lter-hbr.288.1
Title:Hubbard Brook Experimental Forest: Hyperspectral Reflectance Imagery, March 2013
Alternate Identifier:DOI PLACE HOLDER
Abstract:

Airborne remote sensing data were acquired specifically for the EPSCoR NH Ecosystems and Society project to provide vegetation biometric and land surface optical properties at the landscape-scale. Data were acquired for targeted field sites that include the Lamprey River Watershed, the Hubbard Brook Experimental Forest and the Bartlett Experimental Forest, where soil and aquatic sensors are deployed and intensive field sample plots have been established to measure a range of vegetation and land surface properties. Two image data collection campaigns were deployed—one in summer (August 2012) to capture peak growing season conditions in the state, and one in winter (Feb/March 2013).

This data package contains the flightlines for Hubbard Brook. Data are georegistered and atmospherically corrected to surface reflectance for March 9, 2013.

Methods and protocols used in the collection of this data package
Description:

Data were captured with the ProSpecTIR-VS, an imaging spectrometer, or “hyperspectral” sensor, that measures radiance in 360 narrow (~5 nanometer) wavelengths ranging from 400 to 2450 nanometers, at 5 meter spatial resolution. The sensor is flown on a fixed wing aircraft at approximately 4100m altitude, and incorporates Inertial Navigation Systems (INS) with fiber optic gyros on micro-electrical mechanical systems (MEMS) based angular rate sensor and MEMS-based accelerometers to provide for accurate geogreferencing of the data. The Inertial Measurement Unit is coupled with a 12-channel GPS system that utilizes Ominstar realtime differential correction to feed the tightly coupled Kalman filter of the INS.

Data products delivered directly from SpecTIR include scaled at-sensor radiance (mW cm-2 sr-1 nm-1), reflectance (unitless), and associated georeferencing models and look-up tables. The reflectance data product is generated using the ATCOR4 implementation of the MODTRAN4 atmospheric model. (Full image product documentation is available upon request.)
