A Few Results

Local Sunshine at a remote location.

The first figure is a graph of data taken remotely from IUS (where we are located) of Edinboro PA (where we've never been). This is a 24 hr period starting Sat. Dec 27 around 10:50 AM. It seems it was cloudy earlier in the day and then sunny (or maybe the probe was facing north and didn't get the morning light).
 

Probes facing different directions

The following two graphs are 24 hr periods from two different probes in the same location, one facing south (solid line), the other facing north (dotted line). Clearly some cloud patterns affect both probes  (the dip in both curves in the first graph) while other patterns do not (dip in solid curve in second graph does not show in dotted curve).


 

How about Saturday's sunshine vs Sunday's in Ticonderoga NY?

The next figure compares sunshine on Saturday, Jan 19th (solid line) with sunshine on Sunday, Jan. 20 th (dotted line) for two, 24 hr periods in Ticonderoga NY (also where we've never been, even to visit!). Clearly it was more sunny on Sunday (NY-2; dotted line). The Sunday data ends a little before the full 24 hrs; we suspected the computer there may have gone down and we confirmed this was the case with someone at the site..

Did we see a lunar transit in NY from IN?

The following two figures are of data collected from NY during the 24 hr period starting at 3:20PM on Jan. 21. Clearly the probe was exposed to a bright light at some point during the night (a little after 11 PM for approximately 8 min.). Can anyone calculate the speed of the moon relative to the earth from this data?

How does the sunshine in Ticonderoga NY compare with Omaha NE?

This figure compares Ticonderoga (solid line) with Omaha (dotted line) for the same 24 hr time period (starting Sat. morning, Jan 19). Hey the sun sets earlier in NY than it does in NE! Can you calculate the speed of the surface of the earth from this data if you knew the latitude and longitude of the two cities? Note that NY must have set the light probe on the middle setting; NE on the higher setting (or the amounts of sunshine were very different).

Bad data or weird weather?

This is data from Edinboro PA on 12/26/98. We don't know if there was something wrong with the equipment or the clouds were weird that day. Data from their site look fine on other days.

Long term sunshine?

The following is a graph of five days of data from Omaha NE. This isn't exactly right because it took a few minutes at the end of each 24 hr period to reset the collection software (but this could be automated). The day after Christmas had the least intense sun it would seem.
