Resistance to peak air temp #23

Closed djhocking closed 9 years ago

djhocking commented 9 years ago

Currently, the peak air temp is for an arbitrary period (dOY that call in the summer). Make a function to do this for the warmest 60 or 90 days of the year for each site and year.

Used zoo and dplyr to calculate rolling means and find the warmest 90 days for each site-year then calculate resistance for that period of time.

Nice! What happens when there are less than 90 days in a year-site combo?

It’s not a problem because I’m using daymet air temperature. That way it’s the resistance of the water temperature to the warmest period of air temperature (i.e. does the water temperature increase or flatten out and become less responsive during peak air temperature periods). I’m also doing it for the predicted stream temperatures so it should be continuous for the day met record.
