The way the readings taken from Sencrop stations are measured comes from considering theory and scientific rigor as much as the experience of our users. New functions are constantly under development to improve their precision, coming as close as possible to the reality and problems faced by farmers.
Collection
The way the stations measure rainfall has been engineered for optimum precision. The precipitation falls into the collector, whose surface area is within the range recommended by the World Meteorological Organization (World Meteorological Organization, 2021). The angle of the collector has been designed to avoid raindrops rebounding out of the receptacle.
Rainfall measurements can be affected by several factors, including wind, evaporation, splashing, and water clinging to the measuring equipment. To address these discrepancies and obtain a more accurate measurement of true rainfall, various algorithms and techniques are employed.
The rain gauge measurement system is a tipping bucket system. Once filtered, water reaches the bucket. A small but sufficient accumulation of water triggers the bucket's tipping, incrementing the rain counter.
The shape of the collector has also been carefully thought out so that the measurement of the rain is as little disturbed by environmental factors as possible. Inside the collector, there is a filter to protect the measuring system from any outside elements and to allow it to be cleaned quickly and easily.
Data correction
We are improving the accuracy of our station's data through a specialized algorithm designed to address issues such as water lingering on the collection surface and evaporation. This algorithm ensures that even minimal amounts of rain are accounted for with precision.
⚠️ Because rainfall patterns vary by location and modeling rainfall accurately is complex, we've chosen not to fill in missing rainfall data intentionally.
