Story from Envisat – Monitoring ozone in the Polar Sky
ESA TV Exchanges
Background information on the transmission:
This ESA TV Exchanges feed is transmitted by the European Commission’s “Europe by Satellite” (EbS) service. You can find the complete transmission schedule and download scripts and shot lists, also for ESA TV items, from the EbS Web site at http://europa..eu.int/comm/ebs/index.html
In early December, ESA’s Envisat satellite is due to be launched on Ariane 5. Today’s transmission is the second of eight ESA TV Exchange Programmes on Envisat’s science and application promises.
This programme features monitoring of ozone depletion from space. It includes a brandnew computer graphics of the year 2001 Antarctic ozone hole, produced by Dutch met office KNMI with data from ESA’s ERS-2 satellite. The data extend until 18 September, thanks to a new ozone forecasting capability of KNMI.
However, although ERS-2 provides very accurate data, it requires sunlight to make measurements. Envisat will carry the Gomos instrument, which uses starlight for measuring atmospheric ozone. This provides more accurate data, and also works during the Antarctic winter. There will be no “black spots” in polar ozone maps any more like today during winter and early spring. This Exchange programme shows how the European Centre for Medium Range Weather Forecasting, ECMWF, prepares for using Gomos data for climate research and ozone forecasting services.
The 5-minute A-roll contains split audio with an English guide track and is complemented by a longer B-roll with clean international sound. The is on-line as of today as a PDF document under http://television.esa.int/photos/EbS21324.pdf and the detailed shot list will be included into the script tomorrow.
