Measuring stations

Classic Weather Stations (EMC)

Measured variables

• Air temperature • Soil temperature • Air humidity • Precipitation • Heliofany• Direction and wind speed (2 and 10 m)• Depth groundwater • Evaporation tank

Intervals:12UTC - 18UTC - 24 UTC






Automatic Weather Stations (EMA)

Measured variables

• Air temperature• Soil temperature• Air humidity• Precipitation• Wind direction and speed (2 or10 m)• Solar Radiation

Intervals:10 min – 1 hs

Instrumentation standards and/or placement.

Prototype Weather Stations (PMC)

Measured variables

• Air temperature • Soil temperature • Air humidity • Precipitation

Intervals: On line






Radar


Technical characteristics

• Band C (5.6 Ghzfrequency, wavelength 5.4 cm)• Double Polarization• Pixel 1km2 • Scanning 10 minutes• Doppler system (120 km)• Range reach 480 km

Access: on line

Radar (Gematronic)






Radar


Reflectivity (DBZ) Rainfall Intensity (mm / h)

Accumulated Precipitation(a day, week, month)

Wind speed (m / s)

Areas hit by hail (% Probability)

Forecast short-term (1 hour) Trajectory storm






Stations are represented as points

Equipment maintenance and damage prevention

The instrumentation of EMC controls, calibration and replacment in case ofdamage is provided by the Central Unit of INTA and National WeatherService.

The EMA is repaired with the intervention of the company who provided the equipment. This is currently organizing a working group to support in electronics, to improve this process control and repair.

The prototype has a very low maintenance. The components are replacedby technical INTA

The radar network is in charge of the company that provided them






Input to other systemsSome of them

• Production Statistics• Monitoring regional weather• Estimate Water Balance • Forecast of crop diseases• Models of development and crop growth• Hydrological models• Radar adjustement and calibration• Forecast of seasonal rains• Agroclimatic zonification• Alert and monitoring of frosts






Setting Up our system – Some problems – Some Innovations

We find difficult the process of homogenization of data from differentsystems

We believe that the greatest challenge is to resolve the communicationssystem. For Prototype stations, is designed a system with GPRS and a wireless link to the point with nearest INTA (for places without coverage). Where it meets the internet to send to the base.

Another technological innovation in our stations system is the incorporationof GPS, which allows for the position and time. The time in UTC.

All innovations are aimed at unifying all systems in a database that isaccessible to Web queries, freight and modifications from the internet.
