Climate data from Environment and Climate Change Canada
The following climate datasets are available on the climate data viewer and climate data extraction tool. In addition, the Canadian Centre for Climate Services provides both a Datamart and an application program interface (API) that will allow you to access these dataset in a bulk and/or automated fashion. Please refer to the documentation on these advanced tools for more information. For other datasets, visit the library of climate resources. More data may be available; contact the Climate Services Support Desk for assistance.

Daily Climate Records (Long Term Climate Extremes)
| Full dataset name |
Daily Climate Records (Long Term Climate Extremes) |
| Dataset description | The Daily Climate Records database, also known as Long Term Climate Extremes (LTCE), was developed to address the fragmentation of climate information due to station changes (opening, closing, relocation etc.) over time. For approximately 750 locations in Canada, “virtual” climate stations have been developed by joining (threading) climate data for an urban location from nearby stations to make long-term records. Each long-term record consists of the extremes (record values) of daily maximum/minimum temperatures, total precipitation and snowfall for each day of the year. See the technical documentation on Daily Climate Records (LTCE) or Frequently Asked Questions on Daily Climate Records (LTCE) for more detailed information on this dataset. |
