Risk:
h = midpoint of the tidal range (geoid sea level) (-0.3 m which estimates the approximate effect of summer wave surge)
f(t) = tide height at time t in meters above the reference datum, tide height predictions were obtained from the OSU Tidal Inversion Software
te = time of emergence
ts = time of submergence
g(t) = solar elevation in degrees at time t from NASA JPL Horizons Software, soalr elevations greater than 50 ° were considered risky
s = constant solar radiation of 1 W/m2
time threshold = 2+ hours of risky conditions in order to be considered risky
*Note this analysis is based on cloud-free and fog-free circumstances reflecting potential (not necessarily real) exposure to high temperature conditions.
Daytime Low Tide = Risky
Daytime High Tide = Safe
File Format for Daily Risk Data:

Risk: in W hr/m
File Format for Monthly Summary of Risk:
Year: YYYY
Month: MM
Max: monthly maximum value of risk in W hr/m
Freq: proportion of risky days per month
