It is then possible to locate the limit of tidal flexing, or glacier hinge line, within less than 100 m, across the entire glacier width ( 10). The Current Radar map shows areas of current precipitation. If the glacier velocity (or gravity term) is continuous and steady throughout the period of observation, the differencing of two such interferograms produces a third interferogram which only contains the tidal signal.
This deformation is the combination of a long-term motion under the driving stress procured by gravity, and a short-term vertical motion induced by tidal forcing from the ocean. Based on data from GPS stations, satellite radar images, seismographs and strong-motion recorders, the fault that caused the 22 February earthquake lies. Warmest (lowest) clouds are shown in white coldest (highest) clouds are displayed in shades of yellow, red, and purple. IN NORTHEAST IOWA BLACK HAWK BREMER IN NORTHWEST IOWA EMMET PALO ALTO POCAHONTAS IN WEST CENTRAL IOWA CALHOUN CARROLL CRAWFORD. The phase variations associated with surface topography and the interferometric baseline were then automatically removed from the interferograms, leaving only phase variations caused by the glacier deformation over 1 day. The United States satellite images displayed are infrared (IR) images. Radar valid at 300 am CDT, Jul 24th 2022. Click on the Layers menu in the bottom right of the radar to select radar options like Current Conditions, Storm. A DEM was registered to each interferogram from a knowledge of the radar imaging geometry and the satellite precision orbits. Track rain, storms and weather wherever you are with our Interactive Radar. View other Northeast LA radar models including Long Range, Base, Composite, Storm Motion, Base Velocity, and Storm Total with the option of viewing static radar images in dBZ and Vcp measurements, for surrounding areas of Northeast. To locate the grounding line with ERS radar interferometry, we used two interferograms formed by combining ERS image data acquired 1 day apart. 1 Hour Rainfall Total Doppler Radar loop for Northeast LA, providing current animated map of storm severity from precipitation levels.
