Message from Director

Japan′s first geostationary meteorological satellite (GMS), known as Himawari (meaning ″sunflower″), was launched in July 1977 to observe typhoons and other atmospheric phenomena. In the four decades since its launch, Japan′s geostationary satellite series has conducted space-based meteorological observation at around 36,000 km above the equator to provide information essential for disaster prevention, traffic safety and daily living.

Today, Himawari 8 and 9 – representing a new generation of satellites featuring highly advanced imagers characterized by a greater number of spectral bands, higher resolution and more frequent observation than ever before – perform meteorological observation that attracts significant international attention.

The Meteorological Satellite Center (MSC) was established in April 1977 as an auxiliary organ of the Japan Meteorological Agency (JMA). MSC carries out operations relating to Himawari, including daily control, observation planning and data collection/distribution. The Center also receives data directly from NOAA′s and EUMETSAT′s polar-orbiting meteorological satellites.

MSC processes these data to create a variety of cloud images and derive products such as information showing distribution of upper-air wind and sea surface temperature. Data from Himawari are also used to monitor cumulonimbus clouds (which bring heavy rain and thunderstorms) as well as volcanic ash and Kosa (Aeolian dust). These products are provided internationally for use in weather forecasts, warnings to mitigate the effects of natural disasters, and monitoring of climate change.

These MSC activities highlight Himawari′s essential role in meteorological/climatological monitoring in Japan and the East Asia and Western Pacific regions as a whole. The products created are also used in a variety of commercial applications to promote economic activity.

The Center remains committed to its responsibility for social contribution by maintaining the continuous operation of the Himawari series and the provision of high-quality satellite data and products.
