研究目的
To propose values of atmospheric transmittance coefficients using heliophany and the difference between maximum and minimum temperatures for a city located in the Andean Ecuadorian zone.
研究成果
The model of Prescott showed the highest correlation coefficient, making it the most recommended for the city of Riobamba. The study also found that relationships with heliophany estimate solar radiation incident better than relationships with extreme temperature differences.
研究不足
The study is limited to the Andean Ecuadorian zone and may not be generalizable to other regions with similar weather characteristics.
1：Experimental Design and Method Selection:
The study involved calculating extraterrestrial radiation and applying statistical techniques to meteorological data.
2：Sample Selection and Data Sources:
Meteorological data measured since June 2007 for a period of almost five years in Riobamba, Ecuador.
3：List of Experimental Equipment and Materials:
Piranometer Li-Co #LI-200SA and data logger NRG Symphonie.
4：Experimental Procedures and Operational Workflow:
Data collection every ten minutes, analysis of consistency, and detection of atypical data.
5：Data Analysis Methods:
Calculation of empirical lineal coefficients between different variables using three models.
