Hardware and software consideration to use near real time MSG-SEVIRI and NOAA-AVHRR images

Abstract

The SEVIRI (Spinning Enhanced Visible and Infrared Imager) sensor on the MSG-2 satellite provides an image every 15 minutes, so the development of a system that can exploit the temporal behavior of the observations of terrestrial half-disc, is crucial for these near-real-time applications. To validate the processing results, we need to use some others sensors, like AVHRR (Advanced Very High Resolution Radiometer) for NOAA-19 satellite. A terrestrial station is required to collect and follow the temporal, spectral, and space evolution of the treated topic of interest. In this research, we realized a ground station, to receive daily data from either HRIT (High Rate Image Transmission from METEOSAT-9 geostationary satellite baptized MSG-2), HRPT and APT (High Resolution Picture Transmission and Automatic Picture Transmission from NOAA-19 polar satellite) real time satellite data transmissions. A motorized dish antenna is used to receive HRPT images. In the APT system, a fixed omnidirectional antenna is used. Some results of acquisition and treatment (by our MSGViewer and PCNOAA developed softwares) are described in this paper. After calibrating each data, we have developed various thematic products, such as, terrestrial Albedo, brightness temperature and others treatments. The data gathered is useful in many remote sensing applications. In this work, we are arrived to receive in real time the APT and the HRPT format of the NOAA-19 satellite and HRIT format from MSG-2 satellite. Different combinations between visible and infrared bands based on images that the NOAA satellite and MSG-2 has obtained through its AVHRR Radiometer and SEVIRI Imager.
