Expected Field Conditions
Sunrise and sunset azimuth angles are calculated based on the approximation equations by Professor Richard B Goldstein (retired) Providence College Math Department*.
Sunrise and sunset times and hourly azimuth angles are calculated based on the equations by C.B.Honsberg and S.G.Bowden, "Photovoltaics Education Website", www.pveducation.org, 2019. The following links are provided for reference*:
A wind barb is a graphical representation of wind speed and direction. The wind barbs on this page use miles per hour (mph) instead of knots (kt). A short barb represents 5 mph, a long barb 10 mph, a penant represents 50 mph. No Wind conditions are represented with just a reference circle. Wind speeds of greater than 0 mph and less than 2 mph are indicated by a reference circle and a staff. Wind direction is a 36 point compass (10° per point, north: 0°, east: 90°, south: 180°, west: 270°). Wind is always blowing "from" the barbs toward the reference circle.
Here is an example of a wind barb representing a 195 mph wind blowing from the WNW (300°)
3 penants * 50 mph/penant = 150 mph 4 long barbs * 10 mph/long barb = 40 mph 1 short barb * 5 mph/short barb = 5 mph total = 195 mph
An azimuth is the angle from north (compass bearing) that an observer must turn to find a celestial body in the sky. The observer then looks above the horizon the celestial body's elevation angle to find the object in the sky. For simplicity only the sun's azimuth angle is graphed to determine when the sun will be positioned behind the pilot's back.
