Help with Wet bulb thermometer with wireless data project

Hi there, i am new to arduino and would like some advice to build the following project.

I want to build an accurate (within+/- 0.3 degrees C) wet bulb thermometer, using temperature and relative humidity sensors.

Using a calculation incorporating the measurements from the sensors, I will be able to determine the wet bulb temperature.

When the wet bulb temperature has reached -3 degrees C or 32 degrees F, I would like the arduino device to send this notification (data) to my cellular phone via sms over the cellular 3G or 4G network.

I would also like to have GPS location detection ,so that I know where the device is located.(for data collection and or theft prevention)

The project would be stand alone and would need to operated by a battery.

If anyone can assist me with this project, by offering some advice I would really appreciate this very much.

Cheers
