 Later will iterate to better region split based on learning ... where is that AI neural net when you need it ? ;-)

+Suggestion:
+Precipitation regions is used for rainfall and for runoff. Data for these regions can be used to make trends in accumulated precipitation,
+see [[http://met.no/Klima/Klimautvikling/Klima_siste_150_ar/Regioner/Ostlandet/|met.no]] - the trend diagram here is made for geographical regions, but the same has been done for the precipitation regions.

+The attached {{kvalobs:kvoss:system:qc2:8hdk376snf09zj37dk82s92:st_land_kyst_gr_tr_nr.txt.gz|file}} identifies each station with its particular precipitation region (number in the NR_NO nedbør region column) as illustrated by the following excerpt:
