GSICS is an international collaborative effort initiated in 2005 by WMO and the CGMS to monitor, improve and harmonize the quality of observations from operational weather and environmental satellites of the Global Observing System (GOS).


GSICS in the Global Observing System

GSICS aims at ensuring consistent accuracy among space-based observations worldwide for climate monitoring, weather forecasting, and environmental applications.


This is achieved through a comprehensive calibration strategy which involves:

- monitoring instrument performances,

- operational inter-calibration of satellite instruments,

- tying the measurements to absolute references and standards, and

- recalibration of archived data.

GSICS delivers calibration corrections needed for accurately integrating data from multiple observing systems into products, applications and services.

GSICS contributes to the integration of satellite data within the WMO Integrated Global Observing Systems (WIGOS) and within the Global Earth Observation System of Systems (GEOSS) of the Group on Earth Observations (GEO).


On line user registration to receive GSICS information

A messaging service has been set up in order to streamline GSICS communication with users.
Please register using the on line registration form . The registration does not require any user name or password, you will only be asked to supply basic contact information. Registering allows you to specify what kind of GSICS information you are interested in receiving, e.g.: quarterly newsletters, announcements of new products and services, operational GSICS product status notices, etc.
