Sea Ice MEaSUREs – Data Products

Now GIS Compatible! The sea-ice data available below draw on more than 11 years of nearly uninterrupted, three-day radar snapshots of sea ice from the RADARSAT-1 satellite (1995-2012) or four years of Envisat data (2008-2012) of the Arctic and Southern Oceans. Small-scale kinematics and deformation data are processed by tracking sea ice on a high-resolution grid. Some original …

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.

Sea Ice MEaSUREs – Common Questions and Applications

What is Sea Ice? The simple answer is that sea ice forms in the sea. That’s when it starts to get interesting. https://youtu.be/KXjb6MRj_5Uhttps://youtu.be/dqbiChZPuKo What is Drift Ice? Drift ice is not frozen to anything stationary, such as a shore, the ocean bottom, or grounded ice. In the Arctic Ocean, where drift ice can move as much …
