Including more data

Since the test run of the HadEX3 codes in July (see last post) we've had submissions of more data from colleagues around the world (Thank you folks!).  Some of these have come in the form of the raw daily Tmax, Tmin and precipitation accumulations, whereas others have been the ETCCDI indices.

We're starting to fill in the land surface of the globe.  The GHCND (HCN only), ECAD, LACAD and SACAD still form a strong backbone in some parts of the world, but these have been supplemented by data from New Zealand, South America, Honduras, Russia, Western Africa (rainfall only), Australia (temperature only so far), North Africa and the Middle East and Pacific Island states.  The latest run of the code has included most of these new sources.  Thank you to all who have contributed data so far, your efforts are very much appreciated.

For the early period, we also have received data from the ACRE consortium to add in.  Naturally, many of these rescued data do not cover the reference period used for the indices based on percentile thresholds (1961-90), but for other indices these provide a valuable increase in the data coverage for the early part of the record.  To tempt you, here are some plots of the current station distribution for a couple of indices.

We know of data over Canada (T), Southern Africa, Australia (P) which we should get in the next couple of months.  If you are able to provide data over China, India, Eastern Africa then the would be wonderful, but, as always, for any data that could contribute, we'd love to hear from you!
