9th November 2011

We have had a lot of requests recently for snow data in the USA and Europe and for solar radiation data in Europe. We have cleaned dozens of snowfall data sets for many of our SuperPack clients (for no extra charge..all part of the service). Solar radiation data can be tough to find in Europe. We can provide HOURLY solar radiation data for sites in the UK, Netherlands and Germany.

 3rd November 2011

UK: We have moved into our new office premises in Harpenden. Our address is the same but we now occupy a complete floor of the building. The new office provides us with a more pleasant and more efficient working space and the room we need to continue growing.

20th October 2011

Recalibrated data sets: We have just issued the latest 6-monthly updates to data packs for key US sites to reflect recent changes at the 24 US CME sites. We have identified significant discontinuities in two stations one of which is more than 2 degrees F.  

19th October 2011

We are pleased to welcome a new employee to our USA office. Adam Frumkin will assist the team with our growing data, forecast and consultancy products. Adam has a Masters in meteology from Florida State University.

We continue to expand our range of historical data sets and feeds. Please see here for recent additions.

European Windstorm data: we have produced an unusually high density historical data set for European windstorms from the 1970s and on. Please contact us for more information.

 
25th May 2011
We are delighted to be helping more clients looking for historical hourly and daily weather data who are disappointed with the response times of the national met offices: we are a private business who understand the importance of rapid response. We carry a huge archive of weather data from around the world and we have the systems to be able to deliver this data as one-off historical data sets or as daily or hourly realtime feeds. 
 
2nd May 2011
We have been fielding a lot of requests for hourly wind data and for snowfall data recently. Other requests over the last two months have been as eclectic as ever including: Indian rainfall; Brazilian hourly wind speed; Chilean rainfall; Austrian temperature; Guatemalan rainfall; Belize rainfall; Finnish temperature; Republic of Ireland rainfall; UK hourly cloud cover, smoothed temperature averages for Croatian sites; Welsh hourly wind speed; hourly sunshine data for South Africa; temperature and solar radiation for South Korea; rainfall for Bulgaria; and extended hourly wind data histories for Texas.
 
7th March
The data team have had a busy quarter fielding an unusually wide range of client requests for weather data and feeds. SuperPack (our open subscription to ALL our data) continues to grow as a result: expansion of our cleaned US snowfall sets; addition of more hourly wind data for UK; expansion of our Swiss data sets; expansion of UK snowfall data sets, Brazilian hourly, Danish hourly, Thai daily, Korean solar radiation and the addition of another US non-government US network. SuperPack provides access to data not already in our archives on a reasonable-request basis. More often than not, we find it!

2nd December: 
- Speedwell Weather System software development update: Click here for an update on what the development team is working on.

Usually for no extra charge.

- SWSConnect: we are seeing more users on SWSConnect which is our web-delivered version of SWS..and so we are responding to requests to add functionality that has always been available on the full version of SWS. With the latest release users can now select El Nino or La Nina years for pricing (logon required)

 

20th November: 
- Recalibrated Data: there seems to be a lot going on with US CME sites in the update this month. For users unfamiliar with the product, these data sets adjust key US and European sites for historic site moves and instrument discontinuities. The difference over a 50 year period can be VERY significant with the biggest magnitude difference being >2.5F on TMin and > 1.6 on TMax DAILY
