OVERVIEW

Since early January 2015, Europe has witnessed an unprecedented influx of refugees
from regions of war and conflict in the Middle East, primarily Syria, Afghanistan 
and Iraq. The rapid allocation of proper resources is the most critical factor in 
the success or failure of any rescue and relief operations, especially in the "hot"
zones. In order to do so, proper tools of predictive analytics mus be available,
specifically for forecasting the intensity and, if possible, the location of the
next refugee influx waves, so that the rescue elements and the logistical support
is properly prepared beforehand.

This package contains a set of data regarding daily refugee arrivals at the Greek
islands of first-reception in teh Aegean Sea, for the most intense period of influx
waves, from the beginning of October 2015 until the mid-January of 2016.

The sources of the data are:
1) For daily arrivals:
	UNHCR Refugees/Migrants Emergency Response (Data mashups)
	http://data.unhcr.org/mediterranean/country.php?id=83
2) For weather: 
	Searchable Weather Database - National Observatory (Greece)
	http://meteosearch.meteo.gr/

The datasets from (1) have already been used in various publications describing 
such predictive analytics models. Detailed description and related conclusions
can be found at:

* Harris V. Georgiou, "Identification of refugee influx patterns in Greece via 
model-theoretic analysis of daily arrivals" (9-May-2016),

AVAILABLE FILE FORMATS

The datasets are available in the following formats (included):

*.xlsx	: MS-Excel/LibreOffice native spreadsheets
*.csv	: comma-separated plaintext spreadsheets
*arff	: WEKA native data source (plaintext)

These data formats are equivalent, i.e., they contain the exact same
sets of data. Normally, at least one of them should be compatible
with any major programming platform (e.g. Matlab, Octave, R) or any
native programming language for arbitrary handling (e.g. C, Java).

FILES AND DATASETS

Root folder:	GR-RWL1-O15J16\

Dataset 1:	Arrivals\(csv,weka,xlsx)
	"GreeceArrivals-01Oct15-16Jan16.*"
		Complete data series for refugee influx arrivals,
		combined for the entire region (sum)
	"GreeceArrivals-FramesLoc-01Oct15-16Jan16.*"
		Multi-day frames with individual sums for four
		major islands: Chios, Kos, Lesvos, Samos

Dataset 2:	Weather\(csv,weka,xlsx,raw)
	"Chios-Oct15-Jan16.*"
		Weather data (temp,wind,gust,w.dir) for Chios
	"Kos-Oct15-Jan16.*"
		Weather data (temp,wind,gust,w.dir) for Kos
	"LesvosPetra-Oct15-Jan16.*"
		Weather data (temp,wind,gust,w.dir) for Lesvos, loc:"Petra"
	"LesvosThermi-Oct15-Jan16.*"
		Weather data (temp,wind,gust,w.dir) for Lesvos, loc:"Thermi"
	"Samos-Oct15-Jan16.*"
		Weather data (temp,wind,gust,w.dir) for Samos

In the second dataset, the "raw" folder contains the complete weather data for
each island (plaintext) with the exact geographical location of the station.
For Lesvos there are two measuring stations, each located near one fo the two
major sea passages: "Petra" in the North and "Thermi" in the East/SouthEast.
