Himawari imagery in SATAID format are disseminated. In addition, numerical weather prediction (NWP) products (GPV: Grid Point Values) and meteorological observation data other than The number of bands of HRIT files is 14 out of 16.Īdditionally, 1 band of high-spatial-resolution and high-bit-rate infrared imagery is disseminated at night. Himawari imagery in full-disk HRIT/LRIT files compatible with MTSAT HRIT/LRIT data* is provided via the service.įiles are disseminated every 10 minutes in principle. Table 1 shows the dataset of the HimawariCast service. The HimawariCast service provides full-disk imagery with this high 10-minute observation frequency. The interval between full-disk observations by Himawari-8 is 10 minutes, which is much shorter than the 30/60 minutes of the MTSAT series. MTSAT-2 imagery distribution services for L-band frequency High-Rate Information Transmission (HRIT)Īnd Low-Rate Information Transmission (LRIT) via MTSAT-1R was discontinued on 4 December 2015.Īs a replacement of these services, JMA started the HimawariCast service which disseminates primary sets of imagery via a communication satellite from January 2015. See Sun Interference Prediction (external link) for details. This phenomenon is referred to as sun interference, and can adversely affect or interrupt transmission. When this happens, radiation from the sun can cause loss or degradation of communications between the satellite and the receiving station.

The sun passes behind the JCSAT-2B communication satellite (C-band) as seen from its receiving station once a day during the equinox season.
