Meteorological Instrumentation Laboratory
The Meteorological Instrumentation Laboratory – LIM of INPE/CPTEC has as its task the preparation, installation, integration, functional testing and calibration of a large number of sensors and environmental measurement research devices for research in all areas of meteorology. Prominent among these devices are sensors for measurement of temperature, atmospheric pressure, humidity, wind, precipitation, solar radiation and water quality parameters, among others. Also included are equipment and sensors for measurements of turbulent fluxes and concentrations of CO2, H2O, atmospheric radiosondes and measurements at sea utilizing oceanographic buoys.
Environmental Metrology
INPE is developing the capability of performing calibrations on the sensors, transducers and meters that are used in research and environmental monitoring in accordance with international standards (ISO, ASTM, ASHRAE, DIN, etc.), furnishing advances to the country in areas where some capabilities are still poorly distributed.
Sistemas de calibração em fase de operação
The system consists of a climatic chamber dew point meter, standard platinum resistance thermometer and a data acquisition system. The temperature standard follows NVLAP - National Voluntary Laboratory Accreditation Program, U.S.. The dew point standard follows that of Lahig - Laboratory Hygrometry INMETRO; and multimeters, that of RBC – the Brazilian Calibration Network, linked to INMETRO. Also used in the area of relative humidity are the standards from the Vaisala salts, following Fine - Finnish Accreditation Service, Finland.
