TrackTrap: Calculate and Visualize Degree-Days for Pest Monitoring
Combines pest trap observations with daily temperatures to
calculate and visualize cumulative degree-days. Temperature inputs
include 'Daymet' <https://daymet.ornl.gov>,
'Open-Meteo' <https://open-meteo.com/>, reports from the California
Irrigation Management Information System ('CIMIS')
<https://cimis.water.ca.gov>, and user-supplied daily weather data.
Degree-days are calculated using the simple-average method with
either an upper threshold applied to the daily mean or an explicitly
selected calculation without an upper cutoff. The first positive
trap count defines the biofix for every pest, with accumulation
beginning on the following day. Negative daily degree-day values
are set to zero. Users can provide temperature thresholds and
optional thermal reference values. Thermal reference
markers and their multiples do not independently establish flight
or generation identities. Complete daily calculations and weather
provenance are retained with the output to support reproducibility.
