Hi!
here is my understanding of your task
After downloading all files, .txt or as csv, i will have to focus on following
6. If you open as CSV files then only focus on column 1 (Date and time), Column 7 (Station Identifier = 24941 on first line above), column 9 (Wind direction = 250 on first line above), column 10 (Wind Speed = 4 on first line above)
i will select data with 'Station Identifier'=24941, 'Wind Direction=250', 'Wind Speed'=4
7. After that you will send excel file, i will analyze this excel file based on given Station identifiers,
Output:
a
i will provide csv file with, Average daily wind direction, Average daily wind speed, between given dates and for each station identifier,
b
it will be for regions,
C
this csv will contain number of days for each column with columns 0-45), (45-90), (90-135), (135-180), (180-225), (225-270), (270-315), (315-360), and region as index
looking forward to hear from you
