JPSS1

JPSS1 is a Japanese meteorological satellite operated by the Japan Aerospace Exploration Agency (JAXA) and the Japan Meteorological Agency (JMA). Launched on October 18, 2006, the satellite carries three instruments that enable it to provide high-resolution data on global atmospheric conditions.

A-1 is the primary instrument on board JPSS1, designed to collect high-resolution images of the Earth's atmosphere, oceans, and land surfaces. This is achieved through a combination of three sensors: the Advanced Visible and Near-Infrared Radiometer Split-Window (AVNIR-2), the Infrared Radiation Interferometer (IRI), and the Super Low Noise Receiver (SLN). The data from A-1 is used to monitor tropical cyclone activities, sea ice extent, and other severe weather events.

The Polar-orbiting meteorological satellite (PMS) instrument package on JPSS1 is designed to measure certain atmospheric parameters such as atmospheric pressure, temperature, and water vapor. JPSS1's orbit is at an altitude of approximately 888 kilometers (550 miles), ensuring its optimal position to capture atmospheric data affecting the Earth's climate.

The Japanese meterological satellite has spotted numerous severe weather events throughout its operational period. JPSS1 provides crucial climate data on meteorological phenomena such as El Niño and La Niña events. Its weather forecasting capabilities are also extensively used in predicting extreme weather conditions. Throughout its lifetime, JPSS1 has verified effective, complementing the forecasting ability of other meteorological satellites.

JPSS1 has completed its mission life, and it was replaced by JPSS2. However, its core data still aids in climatic upgrade assessments.
