Available parameters differ depending on the station network and obtype. The information below should help when deciding what parameters to specify.

1. Minute Data
   
2. Hourly Data
   
3. Daily Data
   

Instantaneous minute observations: (obtype='O')

Instantaneous / calculated hourly observations: (obtype='H')

Daily observations (obtype='D')

NOTE: Daily data from minute and hourly reporting networks are calculated from respective hourly/minute observations. Generally, the daily minimum, daily maximum, and daily average is available for each parameter. As an example for daily ASOS temperature and pressure data, you could do something like this:
