If the gaps are more than a day, I don't think that NREL fills it (near
real-time weather data providers). You can get data from NCDC as well:
www.ncdc.noaa.gov . When I just checked for MSP, they have data up until
early August 2011. As far as the number of hours available in each month,
726580 14922 MINNEAPOLIS/ST.PAUL 2009 1055 957 1053 997
925 990 963 1052 903 1262 944 1198
726580 14922 MINNEAPOLIS/ST.PAUL 2010 1098 1047 1027 897
998 1074 1003 983 1008 957 1065 1224
726580 14922 MINNEAPOLIS/ST.PAUL 2011 1270 1044 1213 1144
1067 1111 1097 330 0 0 0 0
Total Surface Hourly Observations Available: 32956
Total Station-Years: 3
Yes, there are missing data but I don't see anything as long as you're
talking about. When I requested this data, NCDC put a price of $40 on it.
The specific data set is: DS3505 - Surface Data, Hourly Global.
