We have just released version 2.0.2.2017p of HadISD on the Hadobs website. The data now cover 1931/1/1 to 2017/12/31.
Downloading the data from the ISD finished on Monday 15th January and the quality control and other processes ran over the following days.
There are 8103 stations in this version of HadISD, a full 2000 more than in HadISD version 1.0.x. However, there have been no changes to the quality control tests over v2.01.2016f.
As always, if you notice anything untoward in the dataset please do get in touch. We intend to run a final version in a few months time if there have been changes to the ISD data in 2017 or earlier years in the intervening time.
We hope to move to monthly updates during 2018, which entail some minor changes to the QC code, but which should not impact the annual update methods. We will post on here in due course when this project is nearing completion.
