Mapping blue-ice areas in Antarctica using ETM+ and MODIS data

Mapping Burned Areas in Tropical forests using MODIS data

1 This paper presents a new burned area product for the tropical 2 forests in South America and South-east Asia. The product is derived 3 from Moderate Resolution Imaging Spectroradiometer (MODIS) mul4 tispectral surface reflectance data and Active Fire hotspots using a 5 novel rare class detection framework that builds data-adaptive clas6 sification models for different spatial regions and lan...

Mapping the grounding zone of the Amery Ice Shelf, East Antarctica using InSAR, MODIS and ICESat

We use a combination of satellite techniques (interferometric synthetic aperture radar (InSAR), visible-band imagery, and repeat-track laser altimetry) to develop a benchmark map for the Amery Ice Shelf (AIS) grounding zone (GZ), including its islands and ice rises. The break-in-slope, as an indirect estimate of grounding line location, was mapped for the entire AIS. We have also mapped ,55% of...

Simulation of Wind Fields at Scharffenbergbotten, Antarctica and their Impact on Blue Ice Areas

Mapping of Ice Motion in Antarctica Using Synthetic-Aperture Radar Data

Ice velocity is a fundamental parameter in studying the dynamics of ice sheets. Until recently, no complete mapping of Antarctic ice motion had been available due to calibration uncertainties and lack of basic data. Here, we present a method for calibrating and mosaicking an ensemble of InSAR satellite measurements of ice motion from six sensors: the Japanese ALOS PALSAR, the European Envisat A...

IceMap250 - Automatic 250 m Sea Ice Extent Mapping Using MODIS Data

The sea ice cover in the North evolves at a rapid rate. To adequately monitor this evolution, tools with high temporal and spatial resolution are needed. This paper presents IceMap250, an automatic sea ice extent mapping algorithm using MODIS reflective/emissive bands. Hybrid cloud-masking using both the MOD35 mask and a visibility mask, combined with downscaling of Bands 3–7 to 250 m, are util...
