“…SAPHIR observations SAPHIR is a cross-track radiometer that observes the earth with a maximum scan angle of 42.968, a 1700-km-wide swath, and a footprint resolution of 10 km at nadir that stretches into a 14 km 3 22 km ellipse on the edges of the swath. The characteristics of the instrument are summarized in Table 1 (adapted from Karouche et al 2012).…”

“…It is a cross-track radiometer that observes the earth's atmosphere with a scan angle of 642.968, a footprint size at nadir of 10 3 10 km 2 , and a 1700-km swath made of scan lines containing 130 nonoverlapping footprints. Details of the instrument and its channel characteristics are described in many publications (Karouche et al 2012;Brogniez et al 2013;Roca et al 2015; see also http://smsc.cnes.fr/ MEGHAT/index.htm for monthly technical updates of the instrument).…”

“…The platform carries four instruments: MADRAS, a microwave imager for the observation of rain and clouds (Microwave Analysis and Detection of Rain and Atmospheric Structures), SAPHIR, a microwave sounder of tropospheric RH (Sondeur Atmosphérique du Profil d'Humidité Intertropicale par Radiométrie), ScaRaB, a wide band instrument for the measurement of radiative fluxes at the top of the atmosphere (Scanner for Radiation Budget), and ROSA, a GPS receiver (Radio Occultation Sounder for the Atmosphere). In this study, we focus on the combined use of SAPHIR and MADRAS observations, whose characteristics are listed in Table 1 together with their in-flight radiometric sensitivities as estimated by the CNES space agency (Karouche et al, 2012). SAPHIR is the main instrument for RH profiling with six channels in the 183.31 GHz strong absorption line of water vapor.…”
