2 Outline Instrumentation standards and/or placement Data handling Equipment maintenance and damage prevention Data logging and retrieval methods Spatial and temporal interpolation methods Use of data as input to other systems Lightning detection, radar, or satellite instruments to estimate weather parameters

and temporal interpolation methods Use of data as input to other systems

3 Instrumentation standards and/or placement National Weather Service (SMN) Measuring stations 3 / 47

4 Instrumentation standards and/or placement Classic Weather Stations (EMC) Measuring stations 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

5 Instrumentation standards and/or placement Automatic Weather Stations (EMA) Measuring stations Measured variables Air temperature Soil temperature Air humidity Precipitation Wind direction and speed (2 or 10 m) Solar Radiation Intervals: 10 min 1 hs 5 / 47

temperature Soil temperature Air humidity Precipitation Wind

6 Instrumentation standards and/or placement. Prototype Weather Stations (PMC) Measuring stations Measured variables Air temperature Soil temperature Air humidity Precipitation Intervals: On line 6 / 47

7 Instrumentation standards and/or placement. Radar (Gematronic) Radar Technical characteristics Band C (5.6 Ghz frequency, wavelength 5.4 cm) Double Polarization Pixel 1km2 Scanning 10 minutes Doppler system (120 km) Range reach 480 km Access: on line 7 / 47

8 Instrumentation standards and/or placement. Radar Reflectivity (DBZ) Rainfall Intensity (mm / h) Wind speed (m / s) Accumulated Precipitation (a day, week, month) Areas hit by hail (% Probability) Forecast short-term (1 hour) Trajectory storm 8 / 47

speed (m / s) Accumulated Precipitation (a day, week, month)

10 Equipment maintenance and damage prevention The instrumentation of EMC controls, calibration and replacment in case of damage is provided by the Central Unit of INTA and National Weather Service. 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 replaced by technical INTA The radar network is in charge of the company that provided them 10 / 47

12 Setting Up our system Some problems Some Innovations We find difficult the process of homogenization of data from different systems We believe that the greatest challenge is to resolve the communications system. 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 incorporation of GPS, which allows for the position and time. The time in UTC. All innovations are aimed at unifying all systems in a database that is accessible to Web queries, freight and modifications from the internet. 12 / 47
