Annandale
Defined in ClassAnnandale. The purpose of this module is to estimate
incoming short wave radiation from daily minimum and maximum temperatures when no other
radiation observations are available. Annandale et al. (2001) developed a simple
emipirical method for estimating transmittance from the daily range of air temperature.
- TauA () - transmittance calculated from the Annandale method.
- hru_SunAct (h) - calculated sunshine hours.
- krs () - location index, interior = 0.16 and coastal = 0.19.
- hru_elev (m) - HRU elevation.
- hru_tmax (*) (°C) - daily maximum temperature.
- hru_tmin (*) (°C) - daily minimum temperature.
- QdroDext (*) (MJ/m^2*d) - daily ExtraTerrestrial direct.
- QdflatD (*) (MJ/m^2*d) - daily clear-sky Qdro (with diffuse) on horizontal surface.
- QdflatE (*) (W/m^2) - 'Qdro' on horizontal surface, no atmosheric attenuation.
- Qdro (*) (W/m^2) - clear-sky direct with GSL and ASL applied.
- Qdfo (*) (W/m^2) - clear-sky diffuse with GSL and ASL applied.
- QdfoD (*) (MJ/m^2*d) - daily average clear-sky diffuse.
- SunMax (*) (h) - maximum sunshine hours.
- QsiA (W/m^2) - interval synthesized short-wave derived from Annandale method.
- QsiD (W/m^2) - daily synthesized short-wave derived from Annandale method.
- QsiS (W/m^2) - synthesized short-wave on slope derived from global Qdro and Qdfo, and
the Annandale method.
