Annual report on GFS GCM performance

A mailing list I receive from UCAR brought news of an addition to the GFS forecast archive “New Dataset: NCEP GFS 0.25 Degree Global Forecast Grids Historical Archive” and links to a web page.

On browsing an excellent general interest snippet appeared

Page 16/17, performance over time for a few parameters of various GCM and with the observation on the GFS useful horizon “Increase is about one day per decade”.

Fast tidal data facility, UNESCO / IOC

A couple of days I spotted a data event worth following up but I needed high resolution tidal data, difficult to find.

UNESCO / IOC have created a facility directly linked to many (768 listed) tidal gauges provided true high resolution data, such as 15 minute and with a record of up to 30 days.

The intent seems to be providing public data for safety and research, such as Tsunami monitoring.
