Solar elevation angle (for a day) Calculator

Calculates a table of changes in the solar elevation and azimuth angles for a day and draws the chart.

Input negative degree for west longtitude and south latitude.
If your local time is on Daylight Saving time, select 'ON' from DST mode.

    Purpose of use
    My company takes vertical imagery from fixed wing aircraft for use in mapping and engineering. Specifications of imagery products often hinge on certain sun angle windows.
    Comment/Request
    I use your 'Solar elevation angle (for a day) Calculator on a daily basis. I would also like to be able to look up a specific sun angle window and see a table that calculates all the dates where that range is possible at a certain location.

    For example, I'd like to be able to look up the city of Seattle, Washington, and specify a sun angle range of 30 degrees to 45 degrees. I would like to see a chart that shows me the dates and times that range occurs for a calendar year.

    Thank you for your website! I use it often!!
