However, understanding tropical precipitation is important for weather and climate prediction, as this precipitation contains three-fourths of the energy that drives atmospheric wind circulation. [3] Prior to TRMM, the distribution of rainfall worldwide was known to only a 50% of certainty. [4] The concept for TRMM was first proposed in 1984.
The support includes state-of-the-art computer facilities, research guidance and familiarisation with MOSDAC data. ISRO is an official data partner of the Committee on Earth Observation Satellites. MOSDAC ensures near real time availability of the SAPHIR data of Meghatropiques mission for the Global Precipitation Measurement (GPM).
GRIB (GRIdded Binary or General Regularly-distributed Information in Binary form [1]) is a concise data format commonly used in meteorology to store historical and forecast weather data. It is standardized by the World Meteorological Organization 's Commission for Basic Systems, known under number GRIB FM 92-IX, described in WMO Manual on Codes ...
Additional data is received from India's constellation of satellites, such as Kalpana-1, Megha-Tropiques and instruments on board the IRS series and the INSAT series of satellites. [11] Data and observations are also reported into the IMD network from meteorological instruments on board Indian merchant navy and Indian Navy ships. IMD was the ...
The Climate Data Analysis Tool (CDAT) is plotting software used in atmospheric sciences and climatology. CDAT is a software used in atmospheric sciences and climatology to display meteorological fields such as pressure, temperature, or wind speeds. It allows to read gridded meteorological data in different formats such as netCDF or GRIB and ...
Data is provided at multiple "levels" of processing, from raw satellite measurements to best-estimate global precipitation maps using combinations of all the constellation observations and other meteorological data. All data from the mission is made freely available to the public on NASA websites. [7]
An atmospheric reanalysis (also: meteorological reanalysis and climate reanalysis) is a meteorological and climate data assimilation project which aims to assimilate historical atmospheric observational data spanning an extended period, using a single consistent assimilation (or "analysis") scheme throughout.
The tropical zones have the highest number of storm events followed by the temperate climate. In a recent study, [13] researchers from 63 countries combined 30-minutes rainfall data in order to estimate the global rainfall erosivity (an index combining the amount, frequency and intensity of rainfall). The arid and cold climate zones have very ...
