Himawari cloud phase
Webb27 apr. 2024 · The cloud-top-phase climatology over the western North Pacific (WNP) has received little attention. Using 3 years (2024–2024) of cloud-top-phase products from the Advanced Himawari Imager onboard the Japanese Himawari-8 satellite, this study examines the seasonal and diurnal variations in the cloud-top phase over the WNP. … Webb10 nov. 2024 · Different cloud-top heights (CTHs) have different degrees of atmospheric heating, which is an important factor for weather forecasting and aviation safety. AHIs (Advanced Himawari Imagers) on the Himawari-8 satellite are a new generation of visible and infrared imaging spectrometers characterized by a wide observation range and a …

Webb14 feb. 2024 · The existence of overlapping cloud layers, such as ice-phase clouds, may obscure the lower-level clouds from view of Himawari-8 (a passive satellite), which results in the underestimation of CTT. The occurrence of multilayer clouds introduces errors into the HSWC algorithm, and we can use a neural network to optimize the algorithm. Webb1 jan. 2024 · Developed here is an algorithm for determining the infrared (IR) cloud-top phase for advanced Himawari imager (AHI) measurements from the Japanese geostationary satellite Himawari-8.
