When running the EP weather converter on custom weather input files, warnings as below occur:
Warning ** Direct Normal Radiation= 1114.8 Wh/m² on date= 3/21 at hour=12
Warning ** Global Horizontal Radiation= 1211.4 Wh/m² on date= 4/ 9 at hour=14
This warnings seem to occur especially, if there has been rapid temperature rise in past few hours with changes in cloud cover, Wh/m² estimates ranging between appr. 1100-1550 in my test examples.
What are reasons for such warnings and what should be done in response ?
