GOES [geostationary operational environmental satellites] provide visible and infrared radiometer data that are used for imaging purposes, radiation measurements, and temperature profiles. GOES satellite imagery is used to estimate rainfall amounts, snow accumulation, and overall extent of snow cover. In addition, satellite sensors detect ice fields and map the movement of sea and lake ice. 4, record 2, English, - visible%20and%20infrared%20radiometer

Streaks or wisps of precipitation, such as water or ice particles, that fall from clouds but evaporate before reaching the ground. 6, record 3, English, - virga
Record number: 3, Textual support number: 1 CONT
Virga is frequently seen trailing from altocumulus and altostratus clouds, but also is discernible below the bases of high-level cumuliform clouds from which precipitation is falling into a dry subcloud layer. It typically exhibits a hooked form in which the streaks descend nearly vertically just under the precipitation source but appear to be almost horizontal at their lower extremities. Such curvature of virga can be produced simply by effects of strong vertical wind shear, but ordinarily it results from the fact that droplet or crystal evaporation decreases the particle terminal fall velocity near the ends of the streaks. Under some conditions, virga are associated with dry microbursts, which are formed as a product of the evaporation. 7, record 3, English, - virga

They are actually altocumulus clouds from which precipitation is falling. Such trails of water droplets or ice particles are called virgae (or sometimes fallstreaks) and, by definition, do not reach the ground. 8, record 3, English, - virga

Fall streaks are the wisps that can sometimes be seen falling below high, thin cirrus clouds. They are ice crystals that fall out of the cloud but evaporate as they fall into drier air below. Fall streaks are analogous to another phenomenon known as "virga," which is rain falling from lower clouds and evaporating before it reaches the ground. 11, record 3, English, - virga

Tant que les gouttelettes, ou les cristaux de glace sont petits, ils restent dans le nuage. Mais leur coalescence conduit à leur chute sous l'effet de la pesanteur. Parfois la précipitation n'atteint pas le sol, l'eau s'évapore en altitude et sous le nuage se distingue une sorte de frange appelée virga. 5, record 3, French, - virga
