trans_total.RdCalculates total transmittance of the atmosphere.
trans_total(...) # S3 method for numeric trans_total(sol_elevation, t, elev, oz = 0.35, vis = 30, p = NULL, ...) # S3 method for weather_station trans_total(weather_station, ...)
| ... | Additional parameters passed to later functions. |
|---|---|
| sol_elevation | Solar elevation in degrees. |
| t | Air temperature in degrees C. |
| elev | Altitude above sea level in m. |
| oz | Columnar ozone in cm. Default is average global value. |
| vis | Meteorological visibility in km. Default is the visibility on a clear day. |
| p | OPTIONAL. Pressure in hPa. Estimated from elev and t if not available. |
| weather_station | Object of class weather_station. |
