Assessing Integrity of Weather Data for Reference Evapotranspiration Estimation

摘要: Procedures and guidelines are recommended for assessing integrity, quality, reasonableness of measured weather data equipment calibration automated electronic agricultural stations. The procedures include calculation hourly 24-h clear sky envelopes solar radiation, validation net radiation measurements using equations, evaluation expected trends relationships between air vapor content temperature. creating equations to account the effects atmospheric water sun angle. adjusting temperature introduced compensate aridity station environment. All simple straightforward, can serve as preliminary “filters” by which scrutinize near real-time flagging networks.
