Weather Data Services

 

Speedwell Weather supplies historical and real time weather data feeds for thousands of sites across the globe. We have direct data supply agreements with a range of national meteorological services and collect data in real time from multiple public sources. We are a single-point of contact for the provision of weather data to the energy, commodity, insurance and weather derivative markets.
SuperPack: Corporate-wide access to our entire worldwide archives of hourly, daily historical weather data and feeds including cleaned data sets for a single annual subscription. Click here for more details.
 
The weather sites and variables available through SuperPack grow continuously: as SuperPack subscribers request new data sets that are not already in our "ready to go" catalogue so that catalogue grows. We carry data for over 100,000 worldwide data sets. With very few exceptions these are all within the scope of SuperPack. This service offers a dramatic simplification of the contractual and legal admin involved in data provision. One contract, one charge covers all.

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 2,000 cleaned historical data sets of temperature and rainfall and some other variables and we clean over 2,000 sites per day. We also provide cleaned hourly data sets and feeds.
 
Quality issues: We believe data cleaning is a very serious business. Our pedigree is defined by the responsibilities implicit in providing weather data for the pricing and settlement of financial market transactions over the last decade-i.e. weather insurance and weather derivatives. This represents the sternest test of data quality and provenance.
- Our cleaning techniques build on a very substantial software infrastructure which, in turn, uses a database storing data for over 100,000 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 understand the importance of data provenance. While clients can request to receive our data as a "best-of" feed, we can also provide data showing the component data types: eg raw synop / cleaned synop / raw climate / edited climate / cleaned climate...etc. The use of such a hierarchy means the user can fully understand which data points have been cleaned. For data downloaded through our web site every data value carries a flag describing its provenance.
 
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.

Standard Historical Weather Data Packs. We have well over 100 different packs of weather data. These include packs defined by country, by sector (eg cotton growing areas) or by weather variable (eg hourly Germany data pack for power market analysts). See here to view our packs and individual site inventory statistics.
These are just some of our data packs:
 
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.

Hourly Weather Data
Hourly Weather Data Packs and individual sites: we carry hourly weather data for thousands of sites around the world and can provide real-time feeds. Hourly data can be cleaned on request.
 
Hourly Temperature Frequency Reports: we can provide reports for any site summarising the number of hours in each temperature bucket by month / year. Click here for an example. Please also contact us for Daily Station Reports, Monthly Summary Data and Rainfall Return Periods data. Click here.
 

Individual Historical Data Sets and Feeds:

Historical Data: We pride ourselves on being able to satisfy the most testing requests for weather data from our archives of 100,000+ data sets. Data can be delivered by email, FTP or through our web-download tool.

 

Weather Data Feeds: we can provide data feeds of sub hourly, hourly and daily data for any weather variable. 

 

Recalibrated Data
 
Recalibrated Data Sets: Our Recalibrated data sets adjust historical temperature series to current conditions. Most sites, especially US airport, display numerous discontinuities. Corrections for discontinuities can make a profound impact on the understanding of the behaviour of a site. 
Recalibrated data sets are available for a range of sites in the USA, Europe, Australia and Japan. Any site can be Recalibrated on request. Please contact us.
 
Real-Time Monitor: a web delivered tool for spotting discontinuities as they happen in the reporting of temperature due to site moves, instrument changes etc. The relationship of a reference site to a synthetic site derived from a basket of surrounding sites is monitored in real-time with information presented in a configurable graphical format. This service is included as part of the subscription to Recalibrated Data Sets.
