1. Data

A small dataset is provided for the reader to experiment with. The observations were performed at Athalassa
(35827 North, 332347 East, height 161m above mean sea level), which is the site of the main radiometric
station of the Meteorological Service of Cyprus. The station location is at a semirural site on the outskirts of
Nicosia, the largest city in the centre of the island. The data covers the period from 1/5/2003 to 31/5/2003 
and it consists of 4 files:

-cyprus data daily.txt
-cyprus data hourly.txt
-cyprusdaily.mat
-cyprushourly.mat

The first two are text files and the latter two are MATLAB variable files. As implied by the filename,
there are two sets of data, one with daily values and one with hourly values.


2. Matlab examples

ch12_example1.m

Using the data provided on the accompanying disk, we will create, step by step, a neural model able
to calculate the daily photosynthetically active (PAR) radiation from sunshine duration data.

ch12_example2.m

This example models the daily total solar radiation as a function of the sunshine duration 
using MATLAB code to split the datasets into training, testing and validation datasets 
following the methodology presented in the chapter
