Traditional methods for acquiring topographic data typically rely on aerial photogrammetry, where measurement of the terrain surface below forest canopy is difficult and error prone. The recent emergence of airborne P-band interferometric synthetic aperture radar(IFSAR), a high-resolution, microwave remote sensing technology, has the potential to provide significantly more accurate terrain models in forested areas. Low-frequency, P-band radar energy physically penetrates through the vegetation canopy and reflects from the underlying terrain surface, allowing for accurate measurement of the terrain surface elevation even in areas with dense forest cover.  3, record 8, English, - interferometric%20synthetic%20aperture%20radar

... the TIROS Operational Vertical Sounder(TOVS)... consists of three instruments : the High-Resolution Infrared Sounder-2(HIRS-2), the Microwave Sounding Unit(MSU), and the Stratospheric Sounding Unit(SSU). These instruments provide global information about the structure of the atmosphere, including vertical temperature and moisture profiles and fractional cloud cover. Using a completely physical-based method for analysis of the HIRS-2 and MSU radiance data, additional information can be derived, including surface skin temperature, total vertically integrated ozone amount, outgoing longwave radiation, and precipitation estimates.  1, record 20, English, - vertical%20temperature%20and%20moisture%20profiles

Outre les données de la couverture nuageuse globale, dont on tire de nombreuses informations, les satellites météorologiques permettent de déterminer de manière opérationnelle, d'une part, la température du sommet des couches nuageuses ou de la surface du globe, lorsque celle-ci n'est pas occultée par les nuages, d'autre part, les profils verticaux de température et d'humidité en tout point de la surface du globe par spectrométrie infrarouge dans certaines bandes d'absorption du milieu atmosphérique; par exemple, dans la bande du dioxyde de carbone (de 13 à 15 mm) pour les sondages de température ou dans la bande de la vapeur d'eau (de 6 à 8 mm) pour les sondages d'humidité; la zone d'absorption minimale, dite fenêtre atmosphérique (11 mm), servant à déterminer la température de surface, en particulier la température superficielle de la mer.  2, record 20, French, - profils%20verticaux%20de%20temp%C3%A9rature%20et%20d%27humidit%C3%A9

The laser(or lidar) velocimeter [lidar=light radar] operates in a fashion entirely analogous to that of the airborne Doppler weather radars likely soon to be available for detecting turbulence in storm cells. As with radars, the device detects air movements by observing the motion of particles suspended in the air and carried with it. The only significant difference is that a beam of coherent infrared radiation is used to scan ahead of the aircraft, instead of a beam(or series of pulses) of radio energy in the considerably longer-wavelength microwave band. The frequency of the back-scattered echoes or reflections undergoes Doppler shift detection by standard heterodyning techniques, which involve comparing the frequency of the reflected illumination with that of the original laser beam. Any reflecting object or material which has motion relative to the transmitter/receiver will cause a detectable shift in frequency, which can be isolated from the transmitter's own proper motion(over the ground) and thus yield a precise indication of the speed at which the air is moving several hundred metres in front of the aircraft. From this data, it is easy to compute what the air speed of the aircraft will be when it reaches that particular patch of air in a few seconds’ time [and hence detect possible turbulence ahead].  2, record 26, English, - laser%20velocimeter
