Microwave sensors are particularly effective for measuring land surface hydrological parameters. Since microwave sensors enable us to observe ground surfaces both day and night, we can observe hydrologic phenomena that show remarkable diurnal variation. Further, an inherent feature of a microwave sensor lies in its wavelength between 1 mm and 1 m(0. 3 to 300 GHz of frequency), making it possible to conduct observations without influence from weather and to detect the scattering information not only at the surface, but also in the volume. Furthermore, we can directly observe liquid water having larger relative permittivity than other physical parameters because the scattering of microwaves heavily depends on relative permittivity. There are two types of microwave sensors : a passive microwave sensor that observe weak microwave signals naturally radiated from the Earth's surface, and an active microwave sensor that measures the backscattering coefficient of the transmitted beam.  2, fiche 1, Anglais, - microwave%20sensor

Tous les objets reflètent, absorbent ou émettent un rayonnement électromagnétique qui correspond à leur composition et à leur structure. Un capteur hyperspectral, fonctionnant à l'aide du rayonnement solaire réfléchi, détecte les spectres particuliers, autrement dit la «signature spectrale» d'un objet, ce qui permet ensuite d'en déterminer la composition.  4, fiche 1, Français, - capteur%20hyperspectral

In weather analysis, a baroclinic atmosphere exists when isotherms exist in an isobaric surface analysis. In a baroclinic atmosphere, there is a horizontal temperature gradient and variation with height of the geostrophic wind(thermal wind).  3, fiche 2, Anglais, - baroclinic%20atmosphere

Soon, after the invention of the barometer, it was found that there were natural fluctuations in air pressure even if the barometer was kept at the same elevation. During times of stormy weather the barometric pressure would tend to be lower. During fair weather, the barometric pressure was higher. If the pressure began to lower, that was a sign of approaching inclement weather. If the pressure began to rise, that was a sign of tranquil weather. There is also a small diurnal variation in pressure caused by the atmospheric tides.  2, fiche 3, Anglais, - diurnal%20variation%20in%20pressure

Si on procède à des mesures fréquentes de la pression atmosphérique, ou mieux encore à son enregistrement continu, on peut déceler plusieurs sortes de variations : [...] L'allure de la variation diurne de la pression varie un peu suivant les régions. Son amplitude dépend surtout de la latitude et de le saison. En altitude, vers 2000 m et au-dessus, on observe plus qu'une oscillation par 24 heures.  1, fiche 3, Français, - variation%20diurne%20de%20la%20pression
