The AIRS project released AIRS version 6 data late last week. Significant improvements in data quality were immediately noticed here at SPoRT after the first image utilizing version 6 data was processed.
The first graphic is a plot of AIRS ozone utilizing version 5 data. You can see the gray regions, which represent gaps in the data and poor quality data due to cloud contamination. The second graphic is a plot of AIRS ozone utilizing version 6 data. There are far less gaps in data and data quality issues.
The last two images show the AIRS ozone and GOES West infrared imagery from 1400 UTC this morning. Focus on the low pressure system just south of the Aleutian Islands and compare the two images. Despite the cloud cover associated with the low pressure system, the AIRS ozone was minimally contaminated by the clouds and a clearer picture of ozone was retrieved. The AIRS project plans to process the entire mission as version 6 data by the end of 2013. Therefore the data quality issues will be addressed for the entire mission back to 2002.
