There are three stages of the data transfer for the Brewer Spectrometer.

At the station each computer computer typically runs one to two (1-2) Brewer Spectrometer. Brewer files are saved in the following location

• Windows¹: C:\Br#xxx
• Linux: /brews/Br#xxx

At 25 minute and 55 minute of each hour.

• All data files up to 75 days old pushed to exp-studies².
• Update AVG files at exp-studies².

At 04:00 UTC.

• Station directory is sync with the program master at exp-studies². This will create an exact copy and delete any items that does not exist
• All data is pushed to exp-studies².

At 16:00 UTC brewnet_year_mover is ran

Experimental Studies (exp-studies) is a server used by the Remote Sensing group for data transferring, data processing and data storage. Exp-studies is used as a middle man for data transfer between the station computers through the firewall into brewnet.

Brewer data files are kept at ~/brewnet/Br#xxx

• All data transfer from and to exp-studies is done on the station computers or brewnet
• At 16:00 UTC brewnet_year_mover is ran
• Bulletin updates every 30 minutes on the hour and 30 minute pass the hour.

Exp-studies also host and processes the data for the bulletin. The bulletin gets updated gets updated every xx:00 and xx:30. The bulletin is a versatile tool with different uses.

• Seeing how old the latest data files are (an indication of there might be an issue with the brewer/computer)
• Plots different instrument of the same site together (an indication of how well the instrument is calibrated)

Notes:
¹ Window computers are to be discounted and to be replaced Linux computers
² exp-studies: Experiential studies is the server used to process and host data between station and brewnet.
