Speedwell Weather supplies historical and real time weather data feeds for tens of thousands of sites across the globe. We have been working in this sector since 1999. Unlike many suppliers who distribute only free, publicly available data, we also have direct data supply agreements with a large range of national meteorological services. This means we are able to offer official Climate Data for many thousands of sites worldwide. We are a single-point of contact for the provision of high quality weather data to the energy, agriculture, commodity, insurance and weather risk markets.

 

Our origins as a weather data provider lie in the weather risk markets where we are the dominant provider of weather data for used for the pricing and settlement of weather-risk contracts. As a result, we understand the importance of data quality. We quality control data from thousands of sites to correct errors and, where necessary and possible, to fill missing values.

 

Over the years we have come across a lot of bad data! ...as a matter of policy, for reasons of quality, we do not deliver data derived from GSOD archives unless specifically requested. If you see a difference between the data we provide and data sourced from other sources we will not be surprised. There is a lot of bad data out there!!!! Please contact us for a detailed explanation of the pitfalls of some commonly used public archives of weather data. These can be different not just in detail but FUNDAMENTALLY.

SuperPack^TM: Speedwell SuperPack makes available an unprecedented range of quality historical weather data and weather data feeds for a single annual fee. The SuperPack licence applies corporate-wide across multiple office locations

 

One contract, one fee, covers all data. SuperPack users have immediate access to a catalogue of over 10,000 data sets - and growing. These data sets are shown on this map tool here. Use this tool to see percentage completeness statistics, to access data tools such as Actuals-Vs-Climatology and the Weather Statistics Extractor; and to download the data directly from the web site. Subscribers can request an unlimited number of historical data sets and real-time feeds by FTP. 

 

The list of weather sites available for immediate access grows continuously: In addition, SuperPack subscribers can also request any data from our secondary archives of many tens of thousands of weather sites around the world. SuperPack subscribers also have access to over 4,000 -and growing- cleaned data sets including official international climate data. 

 

SuperPack offers a dramatic simplification of the contractual and legal admin involved in data provision. Click here for more details.

 

SuperPack-Light. SuperPack-Light is for sophisticated weather data users, including those following the agri-markets, who require large volumes of high quality world wide data but who do not need the full-service provided under the full SuperPack subscription. SuperPack-Light is a corporate-wide subscription delivering to up to a maximum of 1,500 user-chosen daily data sets by FTP which can be selected from over 10,000 data sets...all at zero marginal cost. SuperPack-Light subscribers also receive access to additional data download from the website and use of web-delivered tools  such as Actuals-Vs-Climatology and the Weather Statistics Extractor

Cleaned Data Sets: Weather data is often incomplete and may contain erroneous values. Our Cleaned Data Sets correct erroneous values and fill missing data. We carry in excess of 4,000 cleaned historical data sets of temperature and rainfall and some other variables and we clean over 4,000 sites per day. We also provide cleaned hourly data sets and feeds.

 

Quality, provenance and auditability: We believe data cleaning is a very serious business. Our origins as a weather data provider lie in the weather risk markets where we have acted as settlement agent in hundreds of over-the-counter weather risk transactions. This represents the sternest test of data quality and provenance.

 

- Our cleaning techniques build on a very substantial software, hardware and human resource infrastructure which builds on a database storing daily and hourly data for over 80,000 worldwide weather reference sites. Our tools alert us to improbable values by the use of methods including proxy testing, analysis of hourly reports and satellite imagery. However, we believe weather data cleaning can never, and should never, be fully automated. Our data cleaning processes are always manually overseen by meteorologists.

 

- We also understand the importance of data provenance. At Speedwell we store our data in a strict hierarchy that provides transparency on issues such as source, reporting convention and quality. While clients can request to receive our data as a "best-of" feed, we can also provide data showing these component data types:

Hourly Frequency Reports

We are able to provide hourly frequency reports for any hourly weather variable and for any period. The most frequently requested product is the hourly frequency report covering a specific year and shown by month. This shows how many hours in temperature interval were recorded in each month of that year. Click here for an annotated example. Hourly Frequency Reports can be provided for any variable for any site for which we carry hourly data. We carry historic hourly data for many thousands of sites in Europe, Australia, Asia and the Americas.

 

Hourly Average Temperature Data Sets ("Climatologies")

Many clients approach us to buy hourly data which they use to calculate an average value for each hour for each day of the year. This is something we can provide saving the costs of buying and handling large hourly data sets. The output is a file with 24 *366 data points and can be delivered by FTP or by email. This can be provided for any variable for any site for which we carry hourly data. The average can be calculated with or without kernel smoothing. The average can be based on any period with 10 years being the most requested. We carry historic hourly data for many thousands of sites in Europe, Australia, Asia and the Americas.

Wind storms: historic data and real-time feeds. We provide historic data for European wind storms reports and can provide hourly data updates by FTP to support verification of insurance claims or for the valuation of CAT-bonds throughout the year. Weather variables we can supply are hourly maximum gust, hourly average wind speed, hourly wind direction and hourly surface pressure. Data is based on both Metar and Synoptic reports. We offer a high density of sites. Please see here for more information.

 

Standard Historical Weather Data Packs. We have well over 500 different packs of weather data. These include packs defined by country, by sector (eg China cotton growing areas) or by weather variable (eg hourly Germany data pack for power market analysts). See here to view our data packs on our map tool. All sites are also available individually.

These are just some of our data packs:
