Please note that this data was generated on Dec 31, 2013 and the last day of data is depend on the day when the data is retrieved from EC website. If one of the last day is 2013-12-30, it doesn’t mean there is no data after Dec 30, 2013. I will update the data once a while to make sure the dataset is up-to-date.

Background

  1. Environment Canada climate data is available in hourly, daily and monthly. However, this is not true for every station. Some may just have daily and monthly data and don’t have hourly data.

  2. Some stations stopped working at some point and don’t have up-to-date data. For these stations, only a period of data is available.

For climate station selection, it’s useful to know which type of data is available from a station and the time period of available data. These information could be compared with simulation period of a model to help select right climate stations.

Solution

Fortunately,  these information could be retrieved from EC website. Following columns was added to the CSV and shapefile published in previous blog

  1. HOURLY_FIRST_DAY: First day of hourly data; will be null if there is no hourly data

  2. HOURLY_LAST_DAY: Last day of hourly data; will be null if there is no hourly data

  3. DAILY_FIRST_DAY: First day of daily data; will be null if there is no daily data

  4. DAILY_LAST_DAY: Last day of daily data; will be null if there is no daily data

  5. MONTHLY_FIRST_DAY: First day of monthly data; will be null if there is no monthly data

  6. MONTHLY_LAST_DAY: Last day of monthly data; will be null if there is no monthly data

Please note that the name of these columns in shapefile is shortened due to the limitation of shapefile on column name.
