The IPHEN project started in 2006 following the instances arisen during the National Phenology Workshop held at CRA-CMA in Rome at the end of 2005. Its main goals are:

- phenology data collection following established international standards
- production and broadcast of analysis and forecast maps of phenological course for different species
- promotion of data/knowledge exchanges between phenologists;
- interaction with other European and international experiences;
- use of phenological and meteorological data to study climate variability and change (in connection with AGROSCENARI research project).

The project involves phenologists belonging to Universities, Agricultural Research Council (CRA), National Research Council (CNR), regional and local agrometeorological services, agricultural extension services, Italian Association of Aerobiology (AIA) and the Italian Agrometeorological Association (AIAM).

At present IPHEN focuses on the following plant species due to their agricultural, allergologic and ornamental importance:
- Vitis vinifera L. (cv: Cabernet Sauvignon e Chardonnay)
- Cupressus sempervirens L.
- Cupressus arizonica G
- Sambucus nigra L.
- Robinia pseudoacacia L.
- Olea europaea L.

The phenological maps production is mainly based on a Normal Heat Hours (NHH) approach (Mariani et al., 2007; Failla et al., 2008), similar to the chill units approach: thermal resources are translated into normal hours sums collected by a given plant species at a given time.
The logical sequence for maps production is:
- data from CRA-Cma network (92 stations partly belonging to the Italian Air Force) are gathered
- daily Italian maps of maximum and minimum temperatures (cells with a resolution of 2x2 km in geographical coordinates) are produced, spatializing station data by means of the Shepard’s method applied to data previously homogenized for height and aspect
- hourly temperatures are obtained for every single map cell by means of the Parton e Logan algorithm (Parton e Logan, 1981; Cesaraccio et al., 2001)
- NHH are produced on the base of hourly temperatures
- NHH sums from a given starting date until the day of analysis are calculated and the corresponding BBCH phase is obtained by means of empirical relations between historical data of both phenology and NHH sums. Hence a first guess maps is produced
- The final maps is the result of a correction procedure fed with data collected by IPHEN observers acting on the whole Italian area.

Forecast maps are based on the reversion of the empirical NHH-BBCH equations applied to the analysis maps in order to obtain NHH sums for the analysis date. Forecast for the first ten days are based on temperature data coming from NOAA global numerical weather prediction model (GFS) for medium range weather forecast. Forecasts until the end of season are based on climatology (ten days maps from 1993-2009 CRA-CMA network time series).

Maps production activity is based on a prototypal software in DELPHI environment developed and managed by the agrometeorological research group of the Crop Science Department of the University of Milan.
