New era for global meteorological observation system

A new type of satellite is designed to gather real-time information to measure rainfall, snowfall and storm forecasting on a global scale (GPM). This is the result of the project of the US space agency (NASA) and Japan (JAXA).

The project, which has been developed since 2005, has now been completed, is delivered to the Japanese side under the designation H-IIA and by the end of February this year it will be launched into the air from the Japanese Tanegashima Space Center.

Designed in accordance with the cooperation with the current satellites, GPM will fly at an altitude of 407km in an orbit 65 degrees above the equator, the data collected rain and snow will be transferred to the earth every time. Every 3 hours, so we will have a panorama of global rainfall.

GPM is the successor and development of the TRMM type of satellite operating since 1997 to measure tropical rainfall at different times of the day as well as tropical storms. GPM has proved to be much more advanced than the TRMM senior.

The sampling method of GPM satellites is similar to that of TRMM but with very modern devices such as radio micrometer, dual frequency radar, electronic cloud system to transmit information. Furthermore GPM sensors also collect data of snowfall and very small rains.

In addition, GPM also helps to monitor and forecast extreme weather events such as floods and storms.

Gizmag magazine said GPM was born on schedule and when launched into the air there will be 60 days to adjust and operate normally.
