About Speedwell Data Products
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. Click here for more information.
SuperPackTM: 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-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. Click here for more information
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:

Weather Data Packs for Renewable Energy
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 80,000+ 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.
Click here for more information
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.
CAT Risk
European Windstorm data sets: we can provide an archive of max
gusts, average wind speed and wind direction with an exceptionally high geographic
granularity and including sub-hourly reports of European
windstorms since 1970.
