SUN package
Computes the solar zenith angle above the sea surface for all grid center locations.
Computation follows Patt and Gregg, 1994, Int. J. Remote Sensing. Code adapted from the Ocean-Atmosphere Spectral Irradiance Model (OASIM).
sun_init_varia creates arrays of up, north, and east vectors sun_sfcsolz computes solar zenith angle above the sea surface +- sun_jd converts calendar date to Julian day +- sun_ephparms computes ephemeris parameters +- sun_nutate computes the nutation in longitude and the obliquity +- sun_sun2000 computes the sun vector in geocentric inertial coordinates +- sun_gha2000 computes the Greenwich hour angle in degrees
