High-performance infrared narrow-bandpass filters for the Indian National Satellite System meteorological instrument (INSAT-3D).

چکیده
This paper describes the design and manufacture of a set of precision cooled (210 K) narrow-bandpass filters for the infrared imager and sounder on the Indian Space Research Organisation (ISRO) INSAT-3D meteorological satellite. We discuss the basis for the choice of multilayer coating designs and materials for 21 differing filter channels, together with their temperature-dependence, thin film deposition technologies, substrate metrology, and environmental durability performance.

Dust Aerosol Optical Depth Retrieval and Dust Storm Detection for Xinjiang Region Using Indian National Satellite Observations
The Xinjiang Uyghur Autonomous Region (Xinjiang) is located near the western border of China. Xinjiang has a high frequency of dust storms, especially in late winter and early spring. Geostationary satellite remote sensing offers an ideal way to monitor the regional distribution and intensity of dust storms, which can impact the regional climate. In this study observations from the Indian Natio...
متن کاملSpectral design of temperature-invariant narrow bandpass filters for the mid-infrared.
The ability of narrow bandpass filters to discriminate wavelengths between closely-separated gas absorption lines is crucial in many areas of infrared spectroscopy. As improvements to the sensitivity of infrared detectors enables operation in uncontrolled high-temperature environments, this imposes demands on the explicit bandpass design to provide temperature-invariant behavior. The unique neg...

Introduction: The study’s main aim is to investigate the long-term variation of Aerosol Optical Depth (AOD). It also aims to show the relationship between meteorological parameters. This study evaluates long-term (2010 to 2021) special and temporal changes over major Indian regions using satellite-based data from NASA’s Terra Satellite. Materials and Methods: This study was carried out during ...
متن کاملA Compact UWB Bandpass Filter with High Selectivity and Dual Notched-Band
A novel compact-sized ultra-wideband (UWB) bandpass filter (BPF) is proposed in this paper. The proposed BPF is highly selective and is able to eliminate WLAN signals from 5.15-5.35 GHz, and downlink of X-band satellite communication signals from 7.25-7.75 GHz. Generally, a multiple-mode resonator (MMR), comprised of a U-shaped line, with two high impedance stubs connected to it, and one steppe...
متن کاملRecent Improvements in Cloud Motion Vector Derivation from Insat
Cloud Motion Vectors were being derived since 1984 from INSAT, using visible imagery for cloud tracking and infrared temperatures for height assignment. The derivation was made at 0600 UTC daily over the Arabian Sea, Bay of Bengal and a limited area of the western and central Indian Ocean. The method used was basically an automated procedure with a manual quality control. INSAT-2A, the first of...
