After a recent reminder on RASP data reuse, it has been found that a particular site (from and has been scraping images and spot data from the free RASP UK site.

When investigated, whilst there was a correct citation, the plots and spot locations were being pulled in large quantities and stored locally. These were to support a third party weather forecast service (not abiding to the reuse policy amongst other aspects).

We are of course a flying community and learning about the weather is important for any pilot.

Hence, build and implementation advice has been given to permit the third party site to build their own RASP setup to support their specific community and website/business.

At the time of publishing, the weather forecast pages for that site are unavailable for critical updates, but it should be up as and when the admin can advise they are operational again.

Legacy spot graphs are changing 17th August 2020
raspadmin on Saturday 08 August 2020 - 11:50:33 |
The legacy spot graphs are changing 17th August 2020 to a revised spot graph function.

There are some small changes to the API used, but the main changes are:

1. Removal of the use of "i", "j" and "k" coordinates - these are now not needed nor supported
2. All graphs support latitude and longitude (lat= and lon=)
3. The use of a model directly is supported, such as UK at 2Km (UK2), Scotland (UKGM) and Wales (UKGW1)
4. Adjustment to the root location of the utilities (adding /graph/ to the URL used)
5. If used, the BGA Turnpoint name is added to the title for clarity
6. A new plot introduced to estimate if there is top cover (blip_cover.php), by using the surface sun percent and boundary layer cloud percent
7. Improved error checking and feedback if the inputs are not as required

In terms of what continues to be the same:

1. Days of the week for the whole of the UK continue to be supported (at 4Km for the forward three days and 12Km for the remainder of the week ahead)
2. BGA turnpoint

The API changes are fully covered discussed HERE.

Power Outage 12/8/2020
raspadmin on Saturday 08 August 2020 - 11:39:24 |
There will be a period of outage for all RASP forcast functions between 00:00 and 06:00 12th August 2020.

The impact is that there will be no plots or graphs in this periods until the power returns and forecast runs are completed (roughly a six hour activity).

If there are no issues, then most runs should have data available by 12:00 on the 12th of August 2020.

The main web site will be available, but will not provide forecast data until runs complete.

Updates will be on twitter at @RASPWeather is usual.

Winter Maintenance Update and Application changes (07-Jan-15)
raspadmin on Wednesday 07 January 2015 - 21:08:35 |
After some server maintenance this week there are some changes to how this RASP system operates and these are as follows:

  • Update of the data source to mrs.stratus.org.uk from www.mrs.labs.bt.com
  • The 2Km data is temporarily unavailable - but will be back in the next two weeks
  • The raw data is now producded from a single source so later days are not available until a bit later on each day

The 2Km data will be back soon along with faster generation when two new servers are brought online later in January 2015.

A second maintenance window will be posted on twitter when the time slot has been confirmed (likely late Jan 2015).

If you spot anything odd then please use the Contact Us page and report what you find.

Many thanks - Darren

4KM for two days and RASP Table changes (16-Feb-13)
raspadmin on Saturday 16 February 2013 - 10:26:40 |
You may have spotted some tidying up this week.

The RASP table page with the 2km data used for today and tomorrow and a re-sized RASP table with slightly larger images. It is hoped they are useful.

The 4Km run is now for two days out as the 2Km runs for today/tomorrow seem to be fairly stable.

As usual, feedback and observations welcome via the Contact Us page.
