Some checks on the hourly data.
Note that time in these plots is UTC (midnight UTC = 1640 local).
According to our expert in these things (Paul Freitag) the differences are probably due to the different SST sensors and their sampling rate. SST1 is a spot sample every 10 minutes, with the time stamp at the end of the hour, e.g., the value marked, say, 1500, is the mean of those at 1410, 1420, 1430, 1440, 1450 and 1500. SST2 is a spot sample every 7.5 min, with the time stamp at the beginning of the hour, e.g., the value marked 1500 is the mean of those at 1500, 1507, 1515,...1552.
The SWR diurnal difference is due to timing. The two time series are from the same sensor. In the em5b.wnd file, the sample marked 1500 is from measurments at 1417-1423, 1437-1443, and 1457-1503. In em5h.rad, 1500 is from 1457-1503, 1517-1523, and 1537-1543.
