Product Summary
GPM/DPR L3 Spectral Latent Heating (1-Month,0.5deg) dataset is obtained from the Dual-frequency Precipitation Radar (DPR) sensor onboard GPM and produced by the Japan Aerospace Exploration Agency (JAXA). GPM Core Satellite carries DPR and a GPM Microwave Imager (GMI).
Main purposes of the GPM are 'Comprehension of horizontal and vertical structure of precipitation systems', 'Acquisition of precipitation particles information' and 'Improvement of accuracy of precipitation by constellation satellite'.
GPM Core Satellite can observe the range from the south latitude about 65 degrees to the north latitude about 65 degrees, and flies Non-Sun-synchronous Circular Orbit at about the 407 km (442 km since Nov. 8, 2023) altitude. To keep the altitude, the Core Satellite does the orbit maintenance maneuver. The interval is about 7-10 days.
The swaths of DPR instrument are 125 and 245 km (245 km since May 21, 2018) (278 km since Nov. 8, 2023) for a Ka-band precipitation radar (KaPR) and a Ku-band precipitation radar (KuPR) respectively. In addition, simultaneous measurements are done at the overlapping of Ka/Ku-bands of the DPR. The GMI instrument is a conical-scanning multi-channel microwave radiometer covering a swath of 904 km (1015 km since Nov. 8, 2023).
In the Monthly Spectral Latent Heating (3HSLH), latent heating of 0.5degree grid and vertical distribution of Q1-QR and Q2 are obtained from DPR rainfall products.
The provided format is HDF5. The Sampling resolution are 0.5degree grid. The statistical period is 1 month. The current version of the product is Version 7. The generation unit is global.
