Find Accurate Weather Logs for Your Astronomy Observations | Natski

[natski]

Hi all,

I have photometry from a number of sources with only very sparse details about the observing conditions at the time. The only information I have is the date, the filter and the longitude & latitude of the observer.

Is there any program or website on which one can enter any latitude & longitude plus a date and it will be able to estimate or reproduce the weather logs for that area? Specifically I need ground temperature, ground pressure and if possible humidity.

Any tips would be very much appreciated,

For that matter, I cannot find anything that would produce the elevation of a given longitude and latitude and would work well with a script...

Thanks, but is there anything where you enter longitude and latitude rather than the name of a place?

Also, the elevation problem remains unsolved. I have found several java scripts on the web but nothing which one could easily link into a code.

Hmm...not sure about lat and long. I think you may have to manually find the nearest town.

...what elevation problem?

Hmm that's a great shame... it would make an automated script somehow impossible (or at least from my point of view).

Elevation problem - I am referring to other problem I posed: is it possible to somehow input long & lat and output elevation of that target (i..e altitude above sea-level). I have found java scripts to do this but nothing which could be linked into a script running on my machine.

I had the same trouble finding elevations from lat/long a few months ago. Then I found the above site. It works quite simply, submit the lat and long in the url and it'll return some XML that includes the elevation.

example:

That is excellent, exactly what I was looking for! Thank-you so much.
