[ncl-talk] Help (Function SPEI and an error message

[Mary Haley]

Hi Syinthia,

I did not realize that function had made it into the reference card. I will
correct this as soon as I can.

There are a few other routines that need to be remove or corrected:


"dim_thornthwaite_n" ---> "thornthwaite"
"dim_ttwpet_n"
​      ​
---> doesn't exist
"dim_spei_n"
​       ​
 --
​
-> doesn't exist


You may want to check out our examples page:

and in particular look at the "Crop: Evapotranspiration; Penman-Monteith
(FAO-56); Thornthwaite" page:
