「ひまわり」による中国寧夏地域の夏季気温の推定例 [in Japanese] Estimation of surface air temperature in summer using GMS IR data around Ningxia, China. [in Japanese]
Access this Article
This study was performed to estimate temperature using GMS IR data around Ningxia, China, as a large area (66, 000km<sup>2</sup>) with only 17 meteorological observation sites.<br>The results are summarized as follows:<br>1) High correlation coefficients between 1.5-m height temperature and surface temperature were obtained. These correlation coefficients have significance of 5% level.<br>2) The estimated 1.5-m height temperature for from midnight to morning was good accurate, but that from daytime to early evening had large error in the large areas that include different land covers, like Ningxia.<br>3) Temperatures at 02:00 am, and 08:00 am. decreased from the northern part to the southern part of Ningxia. The isotherm was almost parallel to the contour line.<br>4) The night temperature (02:00 am.) in irrigated areas and a reservoir was warmer than that of the surrounding area, morning temperature (08:00 am.) was colder than that of the surrounding area.
