Predictions of the rate of RSL rise due to GIA effect at PSMSL locations

Predictions for ICE-5G (VM2 L90) model (version 1.3) for PSMSL tidegauge sites (in ASCII format). (Note: version 1.3f was here for a short time in error. It is an experimental version, not a fixed one.)

The files were updated Aug 13,2012 using the latest PSMSL station list- no change has been made to ICE-5G since March 2012.

 

Files contain values of the rates of relative sealevel rise and of vertical motion of the solid earth in mm/yr Each shows the coordinates of PSMSL stations followed by 3 columns showing rates-of-change:

(1) a value using the predicted difference in rsl for the last 250yrs 
(2) a value using the predicted difference in rsl for the coming 250yrs 
(3) a value centred on "now" using the predicted rsl at now +/- 250yrs

Obviously (3) is the average of (1) and (2) and we suggest you use this number. The other two can give some idea of how smooth the predicted variation is (but is definitely not to be called an error-bar!)

AN ERROR WAS DISCOVERED IN March 2012 AND THE FILES HAVE BEEN REPLACED WITH CORRECTED VERSIONS.

There are 4 netcdf files giving values (also corrected) on a 1x1 degree grid: 
rate of sealevel rise 
rate of vertical motion 
rate of change of geoid 
horizontal velocity components

Users of the data sets that define the ICE-5G(VM2) model and that have been produced by employing it to make predictions of geodetically and geologically observable signals in the Earth system are requested to reference the following publication in which this model was originally presented:
