|This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. Davis stations calculate Sea Level Pressure from Station Pressure using a formula based on several parameters such as temperature, humidity, etc, rather than just using altitude as most other stations. CWOP require 'Altimeter Pressure' to be uploaded, i.e. a value calculated simply using altitude. | |This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen.

'''Note for MX''', use of the LOOP2 (see [[Cumulus.ini_(Beta)#Section:_Station| here]]) means s.l.p. can be obtained from the Davis station. | |||
'''The following note applies to Cumulus 1.x.x:''' The station does not provide this value directly, nor the station pressure, so Cumulus 1.x.x has to read some extra data once a minute in order to do the calculation. This can take several seconds, so it means that a 'normal' data reading may be missed. | |||
If you don't use CWOP, or you are happy for Cumulus to send Sea-Level pressure to CWOP (the difference is small unless you are at high altitude), set this value to 0. | If you don't use CWOP, or you are happy for Cumulus to send Sea-Level pressure to CWOP (the difference is small unless you are at high altitude), set this value to 0. |
