The Weather Source Database

Whether you need basic weather data for one location or comprehensive hard to find weather information for thousands of sites, The Weather Source Database can deliver what you need. Data access fees start as low as $75. Service includes a consultation with Weather Source experts to help ensure you get the best information for your needs. Here is a list of supported weather information.

The Weather Source database is a one-of-a-kind database of weather information built from a combination of multiple datasets merged into one comprehensive "super" database of weather information unlike anything else on the market today. By merging together numerous different datasets, voids in one dataset are often filled by one of the other datasets, resulting in database that has higher data densities and is more complete than any of the original datasets. In addition all candidate data are quality controlled and corrected where possible before being accepted into the Weather Source database. The end result is a "super" database that is more complete and more accurate than any other weather database in existence - period!

It is this "super" database that is at the core of all Weather Source products and services. You can rest assured knowing that the products and services obtained through Weather Source are the best available.

Weather Frequency Analysis

Weather Source provides two different analysis services designed to provide information on how often certain weather occurs.

Our Weather Binning Analysis assigns weather events into bins and then uses the bin counts to determine the frequency at which each weather event occurs.  In this figure we see an example of an analysis for wet bulb temperature. First the wet bulb tempereratures are organized in 1 degree bins. Then the bin counts are determined by counting the number of occurrences where the wet bulb temperature was greater than or equal to the bin threshold.

Finally the percent frequency of occurrence is determined by dividing the number of occurrences for each bin by the total number of possible occurrences.  

The Weather Source GPD Analysis is used to determine the return level and return period for extreme weather events. The analysis is based on the Generalized Pareto Distribution (GPD) method for determining return periods for extreme events.  This figure is an example of a return period plot for maximum daily wind speeds. Typically we provide the return levels for return periods of 10, 25, 50 and 100 year events, but our analysis is flexible to accommodate producing a return level for nearly any period you require.

Forensic Weather Analysis

By bringing together historical weather observations and satellite and radar information we can produce a comprehensive and accurate analysis of past weather for virtually any location. An advantage to using multiple sets of weather information is that each piece of information helps support other information to convey what the weather really was. Manned weather observations are verified by satellite and radar and vice versa such that the whole analysis becomes indisputable evidence of what the past weather truly was. In most cases we can produce accurate analysis of what the weather was in an area about the size of a square mile and on time intervals down to a few minutes. We can also provide expert testimony of completed analyses.

Weather Impact Analysis

You know weather impacts your business. We can help you quantify and manage negative weather impacts and maximize the advantages of positive weather. The result: more control, less weather risk and higher profits.
