Historical data and ongoing feeds are sourced directly from relevant National Meteorological Services. For each country, we have an agreement in place such that we are able to obtain the highest quality data. Upon processing the data into our database the data is cleaned in order to fill missing values and detect and replace erroneous observations. The cleaning process is performed upon historical data with data feeds being cleaned on a daily basis. The result of this process is a dataset ready for your use.
