Climate Observations
In the Climate Observations division we study the global and regional atmospheric composition using satellite observations of trace gases, aerosols and clouds. The observations contribute to monitoring and research of Climate, Ozone, and Air Quality. The main satellite instruments used in our division are OMI, GOME, GOME2, SCIAMACHY and SEVIRI. We develop calibration and retrieval algorithms for these instruments, and process and distribute the satellite data to users, e.g. via TEMIS, in collaboration with international partners. To validate the satellite observations and to provide local monitoring we also operate several ground-based instruments, like the Brewer, the ozone sonde and the NO2 sonde. Our division has the Principal Investigatorship for the Dutch-Finnish instrument OMI, launched in 2004 on NASA's EOS-Aura satellite, and for the Dutch-ESA instrument TROPOMI, to be launched early in 2016 on ESA's Sentinel-5 Precursor satellite.

2014-08-25: Spatial regression analysis on 32 years of total column ozone data

Multiple-regression analyses have been performed on 32 years of total ozone column data that was spatially gridded with a 1×1.5 resolution. The total ozone data consist of the MSR (Multi Sensor Reanalysis; 1979-2008) and 2 years of assimilated SCIAMACHY ozone data (2009-2010).


2014-07-15: OMI 10 years in orbit

On 15 July 2014 we celebrated at KNMI the 10-th anniversary of OMI, the Ozone Monitoring Instrument.


2014-07-10: Contiguous polarisation spectra of the Earth from 300 to 850 nm measured by GOME-2 onboard MetOp-A

In this paper we present the first contiguous high-resolution spectra of the Earth's polarisation observed by a satellite instrument. The measurements of the Stokes fraction Q/I are performed by the spectrometer GOME-2 onboard the MetOp-A satellite.
