I'm trying to collect weather data for a specific location. Can I use data measured somewhere else as long as I enter the correct coordinates of my location in the file header or the corresponding *.AGD file?
In general, no. In order to correctly evaluate the amount of solar radiation incident on a surface with specific orientation and inclination, WUFI must reconstruct the altitude and azimuth of the sun at the moment of the measurement, so it needs the coordinates of the place where the measurement was performed. If other coordinates are entered, the computed solar positions in the sky will not be consistent with the measured data and the conversion will simply give erroneos results. Taking solar radiation data from a close-by location (say, up to 100 km or so away) will be no problem, however.
See question 24 for details.
Other data than the solar radiation can be taken from arbitrary locations; it is up to you to decide whether this makes sense.
