STATA: Collapse daily observations into monthly observations

Here, I teach how to extract months from daily weather dataset, drop (or keep) relevant months, and collapse by month and year

Hi, how can you collapse the daily percentile observations and calculate the percentile indicators on a monthly base? E.g. number of days per month for which daily precipitation was above 99 percentile; number of heat wave days per month; monthly average temperature etc?

Hello, Can you please explain to collapse hourly observations into (total) daily observations
