Tropospheric Ozone Satellite Data

1 introduction over the last several decades.

Tropospheric ozone satellite data.

The merra 2 ozone observing system is relatively simple with sbuv data assimilated between 1980 and 2004 and aura observations omi and microwave limb sounder mls used afterward. Both the gmi simulation and satellite measured tropospheric ozone during the latter aura time period show increases of 3 du decade 1 over the n atlantic and ne pacific. The gmi simulation and satellite data also reveal a tropospheric ozone increases in 4 to 5 du for the 38 year record over central africa and the tropical atlantic ocean. This technique called the tropospheric ozone residual or tor determined the quasi global extent of tropospheric ozone by subtracting the stratospheric column ozone from one satellite from the total column ozone determined from a different satellite.

Both the gmi simulation and satellite measured tropospheric ozone during the latter aura time pe riod show increases of c3dudecade1 over the n at lantic and ne pacific. Please address jerry ziemke jerald r ziemke nasa gov involving problems or specific questions about the datasets. A link to a new ozone profile product from gmao assimilation has been added below. Aura omi mls tropospheric ozone data from nasa goddard space flight center.

The merra 2 reanalysis provides a climate data record of global meteorological and ozone fields from 1980 to present. The original monthly mean clear sky measurements ziemke et al 2006 are still being provided and updated.
