The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
Ku-band Radar Altimeter - IceBridge also carries a Ku band radar altimeter, which can penetrate snow layers to measure sea and land ice surface elevation. [11] Accumulation Radar - The accumulation radar instrument is used to gather high-resolution data on the top part of ice. Looking at the uppermost part of ice allows researchers to map past ...
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
The map from NASA's Earth Observatory land surface temperature changes across America compared to 2001-2010 average for the same day period, stretching from December 26, 2017 to January 2, 2018.
While most polar vortex forecasts are often unpredictable, Fox Weather said this round of cold is different. “This is a very highly confident forecast.
The Polar-orbiting Operational Environmental Satellite (POES) is a constellation of polar orbiting weather satellites funded by the National Oceanic and Atmospheric Administration (NOAA) and the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) with the intent of improving the accuracy and detail of weather analysis and forecasting.

The first weather satellite to be considered a success was TIROS-1, launched by NASA on April 1, 1960. [5] TIROS operated for 78 days and proved to be much more successful than Vanguard 2. Other early weather satellite programs include the 1962 Defense Satellite Applications Program (DSAP) [6] and the 1964 Soviet Meteor series.
Radar astronomy differs from radio astronomy in that the latter is a passive observation (i.e., receiving only) and the former an active one (transmitting and receiving). Radar systems have been conducted for six decades applied to a wide range of Solar System studies. The radar transmission may either be pulsed or continuous.
