Atmospheric Infrared Sounder (AIRS) monthly data are now in Giovanni-4

Data parameters include atmospheric temperature, water vapor, geopotential height, radiation, & cloud properties

Atmospheric Infrared Sounder (AIRS) monthly data are now in Giovanni-4

AIRS monthly air temperature, July 2007, for the United States, at 850 hPA - plotted with Giovanni-4.

Atmospheric Infrared Sounder (AIRS) monthly data are now in Giovanni-4

The Goddard Earth Sciences Data and Information Services Center (GES DISC) has successfully added 40 selected variables for Aqua AIRS Version 6 monthly data to the next generation of Giovanni, Giovanni-4 (G4). These AIRS variables can be viewed at this link: AIRS monthly data variables in G4. The monthly data augment the daily data that have already been incorporated into G4. 

This work significantly benefits AIRS data users for three notable reasons:
  •    It doubles the number of Aqua AIRS data variables available in G4.
  •    It avails AIRS data users G4 performance improvements for monthly data analysis.
  •    It makes the most recent AIRS data version available in Giovanni.

With 80 variables now available for Aqua AIRS Version 6 (daily and monthly) in G4, users of the system can visualize and analyze the structure of atmospheric temperature, water vapor, geopotential  height, radiation, cloud properties, and atmospheric compositions, for the entirety of the Aqua AIRS data record (2002 – present).


One useful aspect of the G4 system is that URLs generated while accessing and analyzing data can be saved and shared, allowing other users to view the same results.   Figure 1 demonstrates this capability. 


AIRS Monthly Air Temp, U.S., July 2007 

Caption: AIRS monthly air temperature at altitudes corresponding to 850 hectopascals (hPA), or approximately one mile above sea level, for the month of July 2007 over the United States. The warmer temperatures in the western U.S. are a manifestation of higher surface elevations. In the west, as the ground surface approaches the 850 hPa atmospheric pressure level, the effects of solar heating are increased. Missing data (grey areas) are where the surface is at a higher elevation and thus lower surface pressure than 850 hPa. Spatial resolution is 1x1 degree.  [Click on the image to view it full-size.]


Generate the same plot as Figure 1 with G4 by clicking on this link, which will take you to the G4 interface with the data and plotting options already selected. Click the green “Plot Data” button to generate the map. Click on the “Feedback” button to submit comments about the data plot to, and request new features or new data products from, the G4 development team.
