A study of clouds in Thailand using ground and satellite based data
Collection: Theses (Ph.D) - Physics / ดุษฎีนิพนธ์ - ฟิสิกส์Type: Thesis(Silpakorn University, 1/7/2022)This research can be divided into three parts. The first part is to investigate the optical thickness of low cloud at Nakhon Pathom station (13.82°N, 100.04°E), Thailand during 2019-2020. A method for determining the ... -
Investigation of the expansion of the tropical zone and its effect on climate in Thailand
Collection: Theses (Ph.D) - Physics / ดุษฎีนิพนธ์ - ฟิสิกส์Type: Thesis(Silpakorn University, 1/7/2022)Amongst the issues associated with global climate change, the expansion of the tropics has become increasingly important. This expansion is normally demonstrated in the form of changes in the Hadley circulation. The first ... -
Estimation of diffuse solar radiation in different wavelength bands using satellite data over Thailand
Collection: Theses (Ph.D) - Physics / ดุษฎีนิพนธ์ - ฟิสิกส์Type: Thesis(Silpakorn University, 12/7/2019)In this work, models for estimating diffuse solar radiation in different wavelength bands namely, erythemal ultraviolet radiation (0.28-0.40 µm), photosynthetically active radiation (0.40-0.70 µm), near infrared radiation ... -
INVESTIGATION OF ATMOSPHERIC WATER VAPOUR IN THAILAND
Collection: Theses (Ph.D) - Physics / ดุษฎีนิพนธ์ - ฟิสิกส์Type: Thesis(Silpakorn University, 18/6/2021)This study aims to investigate the nature of water vapour in Thailand. The study comprises five parts. The first part is to develop a simple empirical model to estimate the precipitable water (PWV). In developing the model, ... -
A study of solar near infrared global and diffuse radiation in Thailand from ground and satellite-based data
Collection: Theses (Ph.D) - Physics / ดุษฎีนิพนธ์ - ฟิสิกส์Type: Thesis(Silpakorn University, 12/7/2019)In this work, global and diffuse solar near infrared radiation (SNIR) were measured at four stations in Thailand namely, the Meteorological Center in Chiang Mai (18.78°N, 98.98°E), the Meteorological Center in Ubon ...
