Meteosat data acquisition

Imagery/Data Acquisition

Imagery acquired every 15 minutes

Cut out for 50 x 50 pixel region over London

Extracted data stored on server 137.24.52/I, linked to R:\dt_data\processed\YYYY\MO\DAY\London

Same format as MSATYYYYDDD.txt but for 15 min intervals

Data Grabbing:

scheduled task RS_data, daily at 0411

Data pulled using D:\Roof\RS\RS_dataGrab.m. This pulls the following for each 15 min interval (i.e. 0000, 0015):

-msg_HRV_rad_London.hdr

-msg_HRV_rad_London.img.gz

-msg_London.hdr

-msg_London.img.gz

-msg_London.txt – the IMPORTANT FILE

Grabbed  I:\YYYY\London\ALL\RS\MM\DD

Data Processing

Scheduled task _RS_dailyFiles, daily at 0422

All 15 minute .txt files merged into one daily file using meteosatGrabber.R. Stored at:

I:\YYYY\London\ALL\RS\DailyFiles\

MSATYYYYDDD.txt

Where data are missing, rows assigned: -99

  • Data Plotting

  • Scheduled task RS_plot, daily at 0433

  • meteosatplot.mplots the data from MSATYYYYDDD.txt for:

  • radiance

  • brightness temp

  • reflectance

  • I:\YYYY\London\ALL\RS\MM\plots

  • Calculated and output to text files:

  • I:\YYYY\London\ALL\RS\DailyFiles\

  • DataSuccessRateDailyTEMP.txt– printed to webpage and diagnostic file

  • DataSuccessRate.txt –appended daily for archival

Success format:

e.g. Success rate: =32.297 %; Number of NA values: 0

To webpage and diagnostic file: ftp_transferdataQual.m

Displayed here

% of 96 x 15 min periods successfully retrieved
