Hi,

Can someone please explain to me eactly what the various parametrers are that I can submit to Wunderground?

windgustmph - what is this? If I have a continuous sequence of instantaneous wind speed measurements from my anemoneter, how do I calculate windgustmph?

windgustdir - what is this? If I have a coninuous sequecne of instantaneous wind direction measurements from my wind vane, how do I calculate this?

windspdmph_avg2m - presumably this is the arithemtic average of all the instantaneous wind speed measurements from the last two minutes?

winddir_avg2m - presumably this is the arithemtic average of all the instantaneous wind direction measurements from the last two minutes?

windgustmph_10m - what is this? If I have a continuous sequence of instantaneous wind speed measurements from my anemoneter, how do I calculate this?

windgustdir_10m - what is this? If I have a continuous sequence of instantaneous wind direction measurements from my anemoneter, how do I calculate this?

Do I have to supply both humidity and dekptf? Surely one can be calculated from the other?

If my software is DIY, what do I report for softwaretype?

Can I calculate a value for "clouds" by procesing the periods of sunshine in previous hours? Or does this really need a human observation?

Is it possible to calculate a value for 'weather' by any sort of automatic observation and calculation, or does this too require a human observation?

How is the figure for UV index calculated? If I use a SI1145 sensor, are the values that this sensor gives compatible with Wunderground?

Thanks - Rowan
