[MITgcm-support] Exf package and interpolation in time

[Martin Losch]

Hi George,

Hi Georges,

your hfluxperiod has to be 100hours (hfluxperiod = 360000.,), if you  
have 100hourly data. The code reads new data every 100h and  
interpolates in-between. You configuration makes the code believe that  
you have data every 150s, so it reads it every 150s (your time step)  
and then runs out of data.
