CEOS organised a tweet chat on satellite data for climate monitoring during COP-21

CEOS, the Committee on Earth Observation Satellites, held a tweet chat on Thursday 3 December, to talk about the role of satellite data in climate monitoring, to accompany discussions during the COP-21 in Paris.

The tweet chat started with a brief introduction from all participants followed by a 1 hour Q/A session.

The tweet chat was well attended by space agencies such as CEOS, ESA, EUMETSAT, CNES and users of satellite data. Their interaction brought together a lot of useful information that is summarised below.

Multiple participants highlighted the importance of satellite observations in order to understand the Earth’s climate. Indeed Earth observation provides globally consistent observations of land surface, atmosphere, and oceans that are difficult to acquire through any other methods.

Satellites provide information at suitable time (days-decades) and space scales (m-km) to investigate climate relevant issues.  Among the 50 Essential Climate Variables 26 are observable from space and EUMETSAT has around 30 years worth of climate data from space.

A lot of useful tips were shared to understand the full value of satellite data for climate monitoring.

There are different portals to access satellite data, and some of the ones mentioned were EUMETSAT’s Earth Observation Portal, CEOS’s data portal, ESA’s EO-Portal.

They all contain very useful information depending on the instrument and the product sought.

A particular focus for discussion was on the importance of satellite data for ocean monitoring. For instance with the European Union’s Copernicus programme, EUMETSAT will play a key role in operating Sentinel-3 and delivering the marine data.

Data from the family of Copernicus Sentinel satellites is distributed through ESA’s Sentinel Online data hub and will also be available via EUMETSAT (Sentinel-3 marine data, Sentinel-4, -5 and -6).

Other participants shared their views and experience and all tweets can be followed under the hashtag #cop21ceos.

The next and last tweet chat will be this Thursday, 11 December, at 2 pm CET and topics covered will be: thoughts on the outcomes of COP-21 and how COP-21 helped in discovering new resources for finding satellite data, products and information related to climate.

Make sure you tune in to follow the discussions.
