The retrieval was conducted using IASI radiance measurements in the 4.3 and 15 micron CO2 fundamental bands. The analysis was restricted to the time period from 2007 to 2018 using measurements of IASI/MetOp-A.</abstract><sumDscr><timePrd cycle="P1" event="start" date="2007-05-29">2007-05-29</timePrd><timePrd cycle="P1" event="end" date="2018-05-18">2018-05-18</timePrd><dataKind>stratospheric temperature retrievals, daily netCDF files</dataKind></sumDscr></stdyInfo><method><dataColl><sources/></dataColl><anlyInfo/></method><dataAccs><setAvail/><useStmt/></dataAccs><othrStdyMat/></stdyDscr></codeBook>
