Met Office station location assistance

July 29, 2014 3 comments

I need help in locating a few Met Office meteorological sites as part of a new project part of making reality open to all. In addition any correction of errors or additional information is welcome. For anyone not aware I have past history of extensive unearthing of similar information via a surfacestations project. This is not  an easy to read post, sorry.

The UK Met Office has relatively recently started publishing moderate resolution meteorological data for a subset of all stations via a web based facility called Datapoint.

We get hourly data for 176 stations, a few wind data only, the rest a mixture of full or partial data

WARNING opening this full blog article will display a long list of data. Read more…

New Paper by McKitrick and Vogelsang comparing models and observations in the tropical troposphere

July 24, 2014 Leave a comment

Looks to be important, more confirmaton of the 1980s shift seen around the world. As I recall Leroux suggested the 1980 step change needed explaining before running off doing projections. Another place to look is FAO and fish population studies, not just the tropics.

Climate Audit

This is a guest post by Ross McKitrick. Tim Vogelsang and I have a new paper comparing climate models and observations over a 55-year span (1958-2012) in the tropical troposphere. Among other things we show that climate models are inconsistent with the HadAT, RICH and RAOBCORE weather balloon series. In a nutshell, the models not only predict far too much warming, but they potentially get the nature of the change wrong. The models portray a relatively smooth upward trend over the whole span, while the data exhibit a single jump in the late 1970s, with no statistically significant trend either side.

Our paper is called “HAC-Robust Trend Comparisons Among Climate Series With Possible Level Shifts.” It was published in Environmetrics, and is available with Open Access thanks to financial support from CIGI/INET. Data and code are here and in the paper’s SI.
