This is a simple comparison of data from 4 entry-level weather stations:
Data from each station are collected by weewx. Each station has its own sqlite database. The
wee_reports utility runs every 5 minutes to aggregate data from the 4 different databases into a single weewx report of day, week, month, and year plots of the data.
Everything is running on a single ARM-based plug computer circa 2011. Operating system is Debian 6. Python is 2.6.6. Weewx is 3.1.0.
Raw values from each station are in comma-delimited text files. These were created by dumping directly from sqlite:
sqlite> .mode csv
sqlite> .headers on
sqlite> .out filename.csv
sqlite> select * from archive;
Data collected as of 11 June 2015.
