Instructions - how to make degree-day and voltinism maps
See also DDRP/DODMAPS User Guide
DDRP web interface for biological control species (funded by DOD SERDP)
Makes maps of potential and attempted number of generations from daily PRISM or MACAv2 data. 1. Select all options starting with species (must be in our library),
For Start Date, generally Jan 1st is used.
For End Date, generally Dec 31st is used.
Otherwise you may want a current date, or date in the near future.
Years <= 2020 use PRISM data, >2020 use MACAv2 forecasts (GFDL-ESM2M RCP85).
Region: the larger the region the longer the processing time.
Diapause: choose whether number of generations is limited by photoperiod response.
If so, set critical photoperiod (CP) parameters.
CP Mean: Hours of daylight at which individuals switch from reproducing to diapausing.
CP Std Dev: how much individuals vary around the CP Mean.
2. After mapmaking has started, click on this link to your output maps directory.
Refresh this periodically, click "Last modified" to see newest maps.
Depending on options selected, output maps that will be made as PNG files include:
DDtotal_YYYYMMDD (cumulative degree days for the date)
Mismatch_YYYYMMDD (Attempted - potential # of generations at that date)
Diapause_YYYYMMDD (Percent of population in diapause based on photoperiod cues)
AttVolt_YYYYMMDD (Attempted # of generations accounting for photoperiod cues)
FullGen_YYYYMMDD (Potential # of generations based only on degree-days available)
Lifestage_YYYYMMDD (all lifestages present for the date)
NumGen_YYYYMMDD (# generations by the date)
