Understanding EPW meteorological flag codes
The EPW specifications state that the meteorological fields will have one of a specific set of data source & uncertainty flag codes.
(I'm referring to page 52 of this document: https://energyplus.net/sites/default/...)
The data source flag codes are supposed to be: A-F, and ?
The uncertainty flag codes are supposed to be: 0, and 7-9 (values 1-6 not used)
However I'm seeing values that are not in these ranges in some sample files.
Example: TMY3 data for Syracuse, NY (https://bcl.nrel.gov/node/79057)
For the first hour's data the codes are:
?9?9?9?9E0?9?9?9?9?9?9?9?9?9?9?9?9?9?9*_*9*9*9*9*9
^^^^^^^^^^^^
It is the last 12 codes which seem to have some inconsistencies with the specifications. Neither an underscore character nor an asterisk seems to be valid...
What does this mean? Am I looking at out of date specifications?
Thanks
