Wetlands MeASUREs

Wetlands MEaSUREs – Product Specification Guide

The Alaska Satellite Facility (ASF) DAAC acquired the MEaSUREs (Making Earth System Data Records for Use in Research Environments) Wetlands dataset from the Jet Propulsion Laboratory in 2012. The dataset contains the first level-2, derived synthetic aperture radar (SAR) products available from ASF. The dataset includes a global-scale Earth System Data Record (ESDR) of inundated wetlands to facilitate investigations on their role in climate, biogeochemistry, hydrology, and biodiversity. This ESDR provides an accurate, consistent, and comprehensive global-scale dataset of wetland inundation and vegetation, including continental-scale, multi-temporal, and multi-year monthly inundation dynamics at varying scales.

Wetlands MEaSUREs – Monitoring Instruments

Spaceborne microwave remote sensing offers effective tools for characterizing wetlands, as microwave sensors are particularly sensitive to surface water and to vegetation structure, allowing monitoring of large, inaccessible areas on a temporal basis regardless of atmospheric conditions or solar illumination. Inundated wetlands can be consistently mapped and characterized with microwave remote sensing instruments, employed alone or in combination.
