Default weather expertise required for an automotive project!

Hi guys,

I'm working on an automotive project where while driving I collect
weather data along the route. It's all very experimental and my task
is to "do something creative" with the data. I can retrieve the
following weather information:

- temperature
- humidity
- pressure
- brigthness

The first three are pretty straightforward but I don't know how the
brightness is really measured, this is what the weather sensor
manufacturer's website says:

"Ambient light level is an analog level relative to exposed visible
light. It is a number from 1 to 1023 (10-bit ADC) where 1 is very
bright and 1023 is very dark. In high daylight the number is 10-200.
Indoors the level is 800-900. The sensor returns a reading greater
than 1000 in low-light conditions." (http://www.sparkfun.com/
datasheets/Sensors/Pressure/USBWeatherBoard-v2.pdf)

The weather and position data is aggregated and averaged every 5
seconds and then sent as a set of 20 data sets after a 100 seconds.

One idea is to present the current weather to the user. This will be
easy if I have very recent data. My question is though, is there some
sort of a threshold value in means of time, like after what time since
my latest data set is it likely that my weather data is not accurate
(I'm kind of asking what's the fastest rate at which weather can
change?).

My other question is, what can I do with the weather data I have at
disposal? What kind of values can I calculate from it?

Your suggestions are appreciated!

Lex
