Cumulus

Cumulus is a program for retrieving, storing and displaying data from an electronic Automatic Weather Station (AWS).

Cumulus will store full weather records, along with daily and all-time records, and graphical data. Cumulus can upload its data to a web server and comes packaged with templated web pages for this purpose. Cumulus also supports automatic uploads to Weather Underground and CWOP/APRS.

Cumulus works with the Davis Vantage Pro and Vantage Pro2 weather stations, and the Oregon Scientific WMR-928 and WM-918 weather stations, and related models.

Note that Cumulus currently has very little support for retrieving data from data loggers - it only reads ‘current’ data, so to get the best out of Cumulus (accurate daily, monthly and annual totals etc) you need to be running it 24 hours a day. Cumulus version 2 will have improvements in this area to remove this need where possible.

Cumulus is in use on our own Davis Vantage Pro2 weather station, and our data are uploaded to our weather website: Sanday Weather. The web template in use there is packaged with Cumulus, and the commented CSS file is included in order that users may adapt it for their own use, changing the colours and background image as desired. You can, of course, write your own web pages from scratch, and use the ‘web tags’ feature to make Cumulus insert your weather data at the appropriate places. See the help file for more details.
