Dear TIGGE users,

I'm Masashi UJIIE, global modeling group of Numerical Prediction Division, 
Japan Meteorological Agency

We are sorry that the current 'Land-sea mask' values (*) in the JMA TIGGE 
data are incorrect.

Although the land-sea mask has not changed in the forecast,  an error in 
our output scheme for TIGGE resulted in the incorrect data.

The problem only with the 'Land-sea mask' values started on 16 December 
2010.
Before the date, the land-sea mask data are correct.

Attachment you will find the current data and the correct data.

We'd like you not to use the incorrect land-sea mask data for your 
research.

We have a plan to both fix the problem and improve our EPS within a few 
months, and we will announce the updates again.

Best Regards

Masashi
