	DATA PRODUCTS Historic Results		SCIAMACHY DATA PRODUCTS AT IUP / IFE BREMEN   Routinely processed data can be found in our SCIAMACHY-Archive. Total ozone data (WFDOAS) and overpass data for WOUDC ground stations can be obtained from http://www.iup.uni-bremen.de/gome/wfdoas/ SCIAMACHY near real time campaign winter 2006, limb and nadir spectra for the detection of ozone, polar stratospheric clouds and other trace gas species. Information and data.     In addition, at IUP we offer campaign-related data, as well as scientific prototype algorithms to derive geophysical parameters on a daily base. Please contact us if you have specific requests.   ozone profiles (limb)  NO2 profiles (limb)  BrO profiles (limb)        NO2, BrO, SO2, HCHO, and OClO columns Using the DOAS method, atmospheric columns of NO2, BrO, SO2, HCHO, and OClO are retrieved from SCIAMACHY nadir measurements at the IUP Bremen. Tropopheric NO2 is available for almost the full operational period of SCIAMACHY. An novel technique to seperate tropospheric from total column is ¨limb-nadir-matching¨: for a limited period tropospheric columns using this technique are also available Stratospheric NO2 is available for selected validation periods   cloud and surface parameters As part of the SACURA project several cloud parameters are computed. More information about SACURA can be found here.     In the framework of MICROS (MerIs Cloud fRaction fOr Sciamachy). Cloud fractions for SCIAMACHY are provided as well as several surface parameters. Data, ATBD and other aspects of MICROS can be found here.   climate gas columns Vertical columns and/or column averaged mixing ratios of atmospheric methane (CH4), carbon monoxide (CO) and carbon dioxide (CO2) derived from the SCIAMACHY near-infrared and visible nadir radiance spectra. Data, documentation and illustrations here:   water vapour Water Vapour is an also a climate gas but is retrieved from SCIAMACHY with another tool. Data, documentation and illustrations here:   OClO profiles For selected periods of time OClO Profiles are available here (from Limb)   campaigns Tropospheric NO2 from SCIAMACHY and GOME for ICARTT Near realtime campaign winter 2006 by IUP Bremen special products Illustrative and educational material and can be found under press-release ...           Institute of Environmental Physics (IUP) Institute of Remote Sensing (IFE) Universität Bremen Otto-Hahn-Allee 1 28359 Bremen Germany
