This chapter covers active sensing of the atmosphere using both ground-based and satellite-borne radars. Owing to the vast expanse of weather, hydrometeors, and atmospheric gases, in situ measurements ...

The European Space Agency’s launch of the Sentinel-1 satellite has made 20-meter resolution radar imagery of the whole planet freely available. The “all-weather, day-and-night supply of imagery of ...

Recent analysis of 2012 airborne radar data NASA collected remotely suggests the data could predict large sinkholes before they occur, such as one that caused evacuations near Bayou Corne, Louisiana.

Remote sensing has become an indispensable tool in monitoring and understanding the dynamics of ocean winds and waves. Recent advances have integrated satellite‐based instruments such as ...

With mist obscuring the sun, and powerful gusts of wind whipping up flurries of snow, everything merges into a white blur. The sun may be hidden, but its harsh glare still forces the eyes into a ...

Active sensing encompasses the use of a transmitter and at least one receiver to measure (sense) the transmission or scattering properties of a medium at radio frequencies. In transmission ...
