ssd2rad

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.
