ssd2rad

Julian day (for northern hemisphere only)

site specific conversion parameters, must be fitted
 to measured data.

a, b, rho

The function converts values of sunshine duration (in hours) to global
 radiation (in \(J m^{-2} s^{-1}\)).

Datasets, constants, conversion factors, and utilities for 'MArine', 'Riverine',
'Estuarine', 'LAcustrine' and 'Coastal' science.
The package contains among others: (1) chemical and
physical constants and datasets, e.g. atomic weights, gas
constants, the earths bathymetry; (2) conversion factors
(e.g. gram to mol to liter, barometric units,
temperature, salinity); (3) physical functions, e.g. to
estimate concentrations of conservative substances, gas
transfer and diffusion coefficients, the Coriolis force
and gravity; (4) thermophysical properties of the
seawater, as from the UNESCO polynomial or from the more
recent derivation based on a Gibbs function.
