About this scraper
Data and metadata for Environment Canada Weather Stations.
The schema is just about designed so that any monthly meteorological variable (max temps, mean temps, precipitation) can be recorded. For the current scraper, monthly means of daily mean min and max temperatures are stored (the source CSV files record many more variables). Pay attention to flags, some data is estimated.
SCHEMA BEING REVISED
In the swdata table the unique key is (id,element,year).
id is a GHCN style 11 character identifier for the station (derived from the identifers that Environment Canada uses). Note: contains non-digits.
Each row contains data for 12 months, columns M01 through to M12.
I use this to analyse temperature changes in the arctic zone, using ccc-gistemp: see this blog post.
