When you create a simple historical summary, the weather variables are summarized by their default aggregation method for all time periods in question. For example, the maximum temperature is the maximum temperature for all the selected time intervals. Precipitation is the mean across the same time time intervals. In many cases, we don’t want the …
The Weather API includes a unitGroup parameter that allows you to specify the units that will be used when returning weather data. This article describes the units within each group. The API uses four group ids to indicate the units that will be used – us, metric, uk and base. us – United States Weather …
Occasionally when reviewing weather data you come across a weather record that simply doesn’t seem right. Perhaps the precipitation is too high based on what you know about the location or perhaps the temperature is too low, and you know because you live there. At other times you may find missing data within your weather …

Visual Crossing combines multiple nearby weather reports into a single hourly report. This is done through interpolation which is a powerful feature of the Visual Crossing system for locations that are not near a major reporting station, or where the geography is such that it can create temperatures changes in a short distance. This feature …
The Weather APIs include a ‘conditions’ field which represents a summary of the key weather features for a particular weather record (be it daily, hourly or subhourly record). How is the condition field calculated? The weather conditions field is created by examining the weather that will be or was experienced during that weather record. If …
