Purpose:
To aid in manipulation and analysis of the continuous climate datasets, a database solution has been developed to house the continuous temperature and precipitation data for approximately 339 climate stations for the time period of 1950-2005.

Supplemental Information:
Background: Climate records frequently have missing data within the complete climate record. These gaps may be short term in nature (over a number of days due to equipment malfunction), or long term (over a period of years, due to station closures). Daily climate records typically have fewer gaps than hourly records, and are usually associated with stations closures. Hourly data sets typically contain more significant gaps, and are usually associated with equipment malfunction or seasonal closings. Harold Schroeter, et. al. (2000) found that many hourly data sets are missing over 40 percent of the data set. Missing data can be estimated, or filled in, using nearby climate stations to create a continuous data set before completing hydrologic modelling tasks. In 2006, the MNR contracted Schroeter and Associates to fill in temporal data gaps associated with climate stations maintained by Atmospheric Environment Service (AES) of Environment Canada (EC). These gaps include daily and hourly precipitation and temperature records in Ontario within the time period of 1950 to 2005. Sources of data used for this project included primarily AES stations in addition to some stations maintained by Conservation Authorities. As many as 1400 stations were considered. In 2007, AquaResource Inc. was contracted to undertake a review of the work completed by Schroeter and Associates. This review involved compiling all climate data processed and generated by Schroeter and Associates into relational databases. The Ontario In-filled Climate Data is a packaged product containing 8 databases of filled temporal data gaps. These filled data gaps include both daily and hourly precipitation and temperature records.
