Preliminary validation of Himawari-8/AHI navigation and calibration
SPIE Proceedings, 2015The next-generation geostationary meteorological satellite of the Japan Meteorological Agency (JMA), Himawari-8, entered operation on 7 July 2015. Himawari-8 features the new 16-band Advanced Himawari Imager (AHI), whose spatial resolution and observation frequency are improved over those of its predecessor MTSAT-series satellites.

Groundstatiions and Processing Software for Himawari-8
33rd AIAA International Communications Satellite Systems Conference and Exhibition, 2015Himawari-8 is a new meteorological satellite covering the Asian region which was successfully launched in October 2014. It generates 450GB per day of remote sensing data, delivering an entire earth disk in 16 spectral channels, covering the VIS, NIR and IR bands. Most remarkably, a complete earth disk is transmitted every 10 minutes.

MTF analysis using lunar observations for Himawari-8/AHI
Earth Observing Systems XXII, 2017The modulation transfer function, or MTF, is a common measure of image fidelity, which has been historically characterized on-orbit using high contrast images of the lunar limb obtained by remote sensing instruments onboard both low-orbit and geostationary satellites.

Hourly GPP Estimation in Australia Using Himawari-8 AHI Products
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020We extended the MODIS 17 algorithm to hourly Gross Primary Product (GPP) estimation for Australia in 2018. AHI 1-km data are available at NASA Earth Exchange (NEX) facility. The high-frequent observation of Advanced Himawari Imager (AHI) enabled us to calculate hourly GPP, which is corresponding to ground observation of carbon flux measured by TERN ...

Status of Himawari-8/9 and Their Synergy with GCOM Series
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Himawari-8/9 are newest geostationary meteorological satellites operated Japan Meteorological Agency since 2015. The AHI of Himawari-8/9 is a visible, near-infrared and infrared imager with higher temporal, spatial and spectral resolutions. Imagery and products from Himawari-8/9 AHI have contributed to the operations of JMA and other meteorological and

Preliminary Evaluation of Himawari-8 Hourly Aerosol Products Over China
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020In this study, the ground measured Aerosol Optical Depth (AOD) at 500nm at ten sites of the AErosol RObotic NETwork (AERONET) in China were collected to evaluate the AOD retrieved from the observations by the Advanced Himawari Imager (AHI) onboard the Himawari-8 satellite.

Ocean color estimation by Himawari-8/AHI
SPIE Proceedings, 2016The Japanese Meteorological Agency (JMA) geostational meteorological satellite, Himawari-8, carrying Advanced Himawari Imager (AHI) has been in regular operation since July 7, 2015. Before the AHI, geostational meteorological sensors hardly observed ocean color due to only one broad band in visible wavelengths and relatively large radiometric noise ...

Characterization of Himawari-8 AHI 3.9-um channel stray light
SPIE Proceedings, 2016The Advanced Himawari Imager (AHI) is the primary instrument aboard Himawari-8 and has 16 multispectral channels, including six visible and near infrared and 10 thermal emissive bands. The 3.9-μm channel imagery of AHI has spatial resolution of 2 km and performs routine full-disk imaging every 10 minutes.

Detecting Active Fires with Himawari-8 Geostationary Satellite Data
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019We developed an algorithm for active fire detection using the Advanced Himawari Imager (AHI) on the Himawari-8 geostationary satellite. The algorithm is based on a stochastic detection model that aims to minimize a cost function derived from the probability density functions of the fire and background pixels.

Urban Thermal Environment Observation Using Himawari-8/Ahi Data
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019The geostationary meteorological satellite Himawari-8 can observe the Earth’s hemisphere on the Pacific Ocean side at 10-minute intervals and around Japan at 2.5-minute intervals. Continuous observation that is impossible using conventional polar orbital satellites can be made.
