Abstract

This collection represents the processing levels used by the CCI project

Introduction

The different processing levels of satellite observational data that are used within the ESA Climate Change Initiative (CCI).

Indicatorback to ToC or Members ToC

IRI: http://vocab.ceda.ac.uk/collection/cci/procLev/proc_ind

Indicators derived from satellite data.

Level 1Aback to ToC or Members ToC

IRI: http://vocab.ceda.ac.uk/collection/cci/procLev/proc_level1A

Reconstructed unprocessed instrument data at full resolution, time referenced, and annotated with ancillary information, including radiometric and geometric calibration coefficients and georeferencing parameters, computed and appended, but not applied, to L0 data.

IRI: http://vocab.ceda.ac.uk/collection/cci/procLev/proc_level2P

Geophysical variables derived from Level 1 source data at the same resolution and location as the level 1 data, typically in a satellite projection with geographic information. These data form the fundamental basis for higher level CCI products.
