VALIDATION OF MIPAS-ENVISAT BYCORRELATIVE MEASUREMENTS OF MIPAS-STR

摘要

We report on the validation of profiles from thernMIPAS-Envisat on-line processor of ESA version 4.61rnwith correlative measurements derived from MIPASSTRrnonboard the high-altitude aircraft M55-Geophysica.rnThe validation is made for the July 22, 2002, orbitrn2051 in the region of the campaign base in Forlí, Italyrn[1] and for several orbits in February / March 2003rnaround Kiruna, northern Sweden.rnThis paper includes a careful comparison of the MIPASSTRrndata with O_3 sondes and with in-situ measurementsrnfrom the Geophysica obtained during ascent, descentrnand occasional dives. To obtain accurate N_2O and CH_4rnprofiles close to the MIPAS-Envisat tangent points wernused the MIPAS-STR measurements of CFC-11 andrnCFC-12 and correlations [2] obtained by the HAGARrninstrument.
