Abstract

This dataset is a gridded 80x40km2 product with a temporal resolution of daily across the equator.

The data is calculated on a convective cloud differential (CCD) algorithm and averaged whereby only the position of the central coordinate is considered.
The tropospheric column can then be calculated by the difference between the stratospheric column and the total column. The stratospheric column being estimated as above the high reaching convective clouds (cloud cover >0.8 and >8km in height). To reduce the error above the clouds from up draught of tropospheric pollution a clean reference region 70°E to 170°W representitive of the latitude band.

For the Total column only cloud free observations are considered (<10%). This method assumes the stratospheric ozone is constant throughout each month and for one latitude band limit the CCD algorithm to the tropics (20°S to 20°N).

GOME-2 is on-board the EUMETSAT satellite MetOp-A which was launched in October 2006.
Build on a design almost identical to GOME, it covers the same spectral range as its predecessor
but with an improved spatial resolution. The nominal ground-pixel size is 80 x 40 km2 with a
global coverage in almost one day (swath of 1920 km). GOME-2 continues the measurement
series started with GOME, and in this project it is therefore used to retrieve total columns and
vertical distributions of ozone. Data are available since January 2007 on an operational basis. A
second GOME-2 instrument has been launched in 2012 on the METOP-B platform, and a third
one will be launched at the end of the decade on METOP-C.
