Description
Eligible duration requires flowering and valid weather; observed eligible duration requires all three.
Ecological observation summaries depend on sampling effort, eligible time, classified counts and missingness policies. Flower-minutes, area-days and observed proportions have different denominators. Observation support is distinct from true abundance, detection probability or a causal biological-control effect.
Eligible duration requires flowering and valid weather; observed eligible duration requires all three.
When to use this tool
Use Pollinator Valid Window Share when checking the stated observation support, exposure, sample or seasonal-gap convention.
How to use the tool and how it works
- Enter durations, flowering, weatherValid, observed. Follow any array-alignment requirements below. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read eligibleDuration, observedEligibleDuration, share, defined. Inspect defined before interpreting the associated values.
Require aligned nonnegative durations and flowering/weather/observed flags. Eligible duration requires flowering and valid weather; observed eligible duration requires all three. Return their ratio, or zero with defined=false if no eligible time.1

}Limitations and assumptions
- Flags are caller assertions; this is observation support rather than pollinator detection probability or a weather-validity determination.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified representative field records and suitable sampling/detection analysis for ecological inference, uncertainty and management.
