9 How we can request data from the data base?

10 By pressing on this spot…

11 How we can request data from the data base? All_values2003_22.5_117.5.txt All_values2003_22.5_117.5.txt Monthly_mean2003_22.5_117.5.txt Monthly_mean2003_22.5_117.5.txt

12 We have applied the same procedure for 1x1 degrees resolution on a regional level

13 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!

14 An Example from AIRSAT: Data from WDC-RSAT (World Data Center for Remote Sensing of the Atmosphere http://wdc.dlr.de) geographical area data set time period

15 daily data in csv ascii format (1 o x1 o analysis) daily maps start animation select coordinates

16 animation

17 Example of total O 3 time series for Xanthi [41.133 o N, 24.883 o E] graph & csv ascii format Since AIRSAT data base is being updated…

18 Data being analyzed: SCIAMACHY WFM DOAS XCO Level 2b (daily-monthly means)SCIAMACHY WFM DOAS XCO Level 2b (daily-monthly means)2003-2005 SCIAMACHY & OMI Tropospheric NO 2 (daily-monthly means)SCIAMACHY & OMI Tropospheric NO 2 (daily-monthly means) 2003-end of project SCIAMACHY Tropospheric HCHO (daily)SCIAMACHY Tropospheric HCHO (daily) 2003-end of project SCIAMACHY Total SO 2 (daily)SCIAMACHY Total SO 2 (daily) 2004-end of project GOME Tropospheric O 3 (daily gridded on 2x3 degrees analysis)GOME Tropospheric O 3 (daily gridded on 2x3 degrees analysis)1996-1998

19 How we could get all these data in one go ?
