We have applied the same procedure for 1x1 degrees resolution on a regional level
The same analysis has been applied to XCO (could be applied to CH 4 & CO total column data) Each cluster includes a statistically significant number of measurements even though XCH 4 data are quite sparseEach cluster includes a statistically significant number of measurements even though XCH 4 data are quite sparse Advantages of AMFIC web data base This analysis enables easier validation of XCH 4 data for selected regions and comparison with model resultsThis analysis enables easier validation of XCH 4 data for selected regions and comparison with model results The user can request either plots or ascii files even for a quick look in a few seconds!The user can request either plots or ascii files even for a quick look in a few seconds!
An Example from AIRSAT: Data from WDC-RSAT (World Data Center for Remote Sensing of the Atmosphere geographical area data set time period
daily data in csv ascii format (1 o x1 o analysis) daily maps start animation select coordinates
