Pollution mapping 13 October 2004     The highest-ever resolution global nitrogen dioxide pollution map has been produced using data from Envisat's SCIAMACHY atmospheric instrument. The team at the University of Heidelberg's Institute for Environmental Physics explain how the map was created, how SCIAMACHY works and what else it can tell us about the state of our air.     Hi-res videos  •  Sciamachy Video Windows Media Player (http://download.esa.int/Archive/wmv/sciamach_13102004_wmphigh.wmv)  •  Sciamachy Video Quicktime (http://download.esa.int/Archive/Quicktime/sciamach_13102004_qthigh.mov) Related news  •  - (http://www.esa.int/esaEO/SEM340NKPZD_index_0.html)  •  Global air pollution map produced by Envisat s SCIAMACHY (http://www.esa.int/esaEO/SEM340NKPZD_index_0.html) Related missions  •  Envisat overview (http://www.esa.int/esaEO/SEMWYN2VQUD_index_0_m.html)  •  ERS 1&2 (http://www.esa.int/esaEO/SEMGWH2VQUD_index_0_m.html)  •  MetOp (http://www.esa.int/esaEO/SEM9NO2VQUD_index_0_m.html) In depth  •  Earthnet SCIAMACHY Introduction (http://envisat.esa.int/instruments/sciamachy/)  •  EO Principal Investigator Portal (http://eopi.esa.int/) Related links  •  University of Heidelberg's Institute of Environmental Physics Satellite Group (http://satellite.iup.uni-heidelberg.de)  •  University of Bremen's Institute of Environmental Physics SCIAMACHY page (http://www.iup.physik.uni-bremen.de/sciamachy/)  •  BIRA-IASB page on SCIAMACHY (http://www.oma.be/BIRA-IASB/Scientific/Topics/Lower/Satellite/SCIAMACHY.html)  •  KNMI (http://www.knmi.com/indexeng.html)
