I have managed to get all my WD logfiles in one Excel Spreadsheet for hole 2011 (523,102 rows. I miss about 2,498 1-minute rows on a hole year - not that bad
Thanks to Windy for a GREAT program
I have found the average values.
Now I got a question about windspeed - what would be the correct average windspeed for the hole year?
Total of windgust diveded by 523,102 rows (gives 3.9 knots)
Total of average windspeed diveded by 523,102 rows (gives 6.6 knots)
