CRU TS Version 4.04 Google Earth Interface


A Google Earth-based interface to the CRU TS dataset.

The interface allows individual half-degree cells to be examined, and for nearby observations to also be found.
The data included are drawn directly from the CRU TS 4.03 dataset and related observation files.
Temperature (TMP), Precipitation (PRE), Diurnal Temperature Range (DTR) and Vapour Pressure (VAP) are available.
In order to use this interface, you will need to have installed Google Earth
You can then open this file in Google Earth: cruts_4.04_gridboxes.kml


News

DTR and VAP have been added, so four variables are available. VAP, as a secondary variable, has both observed and synthetic station support. The interface has been redesigned accordingly, with new station markers and a proper legend. Station names are hidden (to reduce clutter) until you mouse over them. Synthetic station counts have been added to the VAP cell data. The smoothed curves have been removed from the annual station plots - they were too intermittent. Note that the two bugs found in June can be seen 'in action' in this release; for the clustering of synthetic VAP stations, please see the 3 June report, and for the clustering of stations around the 99.99°W meridian please see the 6 June report. Finally, the colourscheme has been altered to one that is theoretically 'coloursafe' - I welcome feedback on this. (June 2020)
Where cells had no stations in range, the annual mean plot was a straight line (from the climatology), this has been replaced with a sample year from the climatology. Where the (PRE) climatology is zero throughout the year, a note is printed instead (September 2019)
The feature by which 'live' stations had a brighter colour is available for this version. (September 2017)
The error by which, if you were on a Mac, running 10.10.0 or later, choosing to view a 'larger' plot crashed Google Earth when you tried to return to the map, has only been resolved for Google Earth; it is reportedly still an issue on Google Earth Pro. (September 2017)
The feature by which 'live' stations had a brighter colour is not available for this version (all stations are bright). However, as a rule of thumb, if the station data end year is 2016, it is very likely to be receiving current updates. (January 2017)
The error by which, if you were on a Mac, running 10.10.0 or later, choosing to view a 'larger' plot crashed Google Earth when you tried to return to the map, has been resolved. Please get in touch if it recurs. (January 2017)
Precipitation plots now show annual total precip rather than average monthly (October 2015)

Notes

  • A new Frequently-Asked Questions (FAQ) page, also linked from every dialogue box in the interface, is here.

  • Unlike the CRUTEM4 Google Earth interface, (link), on which this is based, the CRU TS Interface needs to have two levels of spatial mapping. So the user is first presented with five-degree blocks, and can click in these to 'turn on' the enclosed half-degree cells.

  • To access the dataset in its original form, please follow links from the HRG page:

  • Users who need more sophisticated access to the dataset are advised to visit both the Climate Explorer at KNMI, which provides interactive access to this and many other datasets, and the Global Climate Monitor at the University of Seville, a newer map-based interface.
