Operational space-based hyperspectral Infrared sounders retrieve atmospheric temperature and humidity profiles from the measured radiances. These sounders like Atmospheric InfraRed Sounder, Infrared Atmospheric Sounding Interferometer as well as INSAT-3D sounders on geostationary orbit have proved to be very successful in providing these retrievals on global and regional scales, respectively, with good enough spatio-temporal resolutions and are well competent with that of traditional profiles from radiosondes and models fields. The aim of this work is to show how these new generation hyperspectral Infrared sounders can benefit in real-time weather monitoring. We have considered a regional extreme weather event to demonstrate how the profiles retrieved from these operational sounders are consistent with the environmental conditions which have led to this severe weather event. This work has also made use of data products of Moderate Resolution Imaging Spectroradiometer as well as by radiative transfer simulation of clear and cloudy atmospheric conditions using Numerical Weather Prediction profiles in conjunction with INSAT-3D sounder. Our results indicate the potential use of high-quality hyperspectral atmospheric profiles to aid in delineation of real-time weather prediction. More »»

M., “Synergistic use of Imager Window Observations for Cloud-Clearing of Sounder Observation for INSAT-3D”, The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, vol. 7, 2014.[Abstract]


The retrieval of atmospheric temperature and water vapor profiles from infrared Sounder are severely limited by the presence of cloud. Therefore, retrieval from infrared sounding observations is performed only over clear-sky atmospheric conditions. The probability of finding a clear-sky pixel at spatial resolution of 10 km is found to be very small globally. This study presents a quantitative analysis of the clear-sky probability that is carried out for different months over the Indian region for INSAT-3D Sounder. The probability of a clear-sky is found to be ~7% for the field of view of 10 km corresponding to the INSAT-3D Sounder. This statistical analysis is established using MODIS cloud mask having 95% confidence level at 1 km resolution spread in the region between 50E-110E and 30S-30N. This necessitates cloud clearing to remove the effect of partial clouds in the Sounder FOV to provide a clear-sky equivalent sounding retrieval. Various methods were explored to derive the cloud-cleared radiances using supplementary information such as high resolution infrared or microwave observations. This study presents an effort to use the existing traditional method to derive optimal cloudcleared radiances for INSAT-3D Sounder, by estimating the fractional cloud cover using collocated high resolution INSAT-3D Imager window channel observation. The final Sounder cloud-cleared radiances have been validated with the operational AIRS L2 cloud-cleared radiance products. Nevertheless, the statistical analysis of clear-sky probability over Indian region also provides a significant insight towards the dependency of spatial resolution and the considerable field-of-regard (FOR) in obtaining the clear-sky area in the satellite observations. This, in a way, necessitates the cloud-clearing for coarser resolution sensors and at the same time, states the benefits of using very high resolution sensors. It has been observed that FOV of 1km and by choosing a reasonably good FOR can eliminate the cloudy-sky hindrances by increasing the probability of clear-sky from 5% to 50% More »»

A series of CuxMg1–xNb2O6 (x = 0, 0.2, 0.4, 0.6, 0.8, 1) columbites were prepared using the sol-gel technique. The samples were sintered at 900 °C for 6 h. The prepared samples were structurally characterized using X-ray diffraction (XRD) method. To study their applicability in low temperature cofired ceramic (LTCC) technology, elastic properties have been characterized for mechanical compatibility. Elastic behavior was investigated at 300K, employing ultrasonic pulse-transmission technique at 1 MHz. The values of elastic moduli and acoustic Debye temperature (µD) were computed from longitudinal and shear velocities. The measured values were corrected to zero porosity using Hasselman and Fulrath's formula. The elastic constants of the samples, estimated using Modi's heterogeneous metal-mixture rule, were also reported. The variation of elastic moduli was interpreted in terms of strength of interatomic bonding. Microstructure of these samples was studied using the FESEM (field emission scanning electron microscopy) technique. Mechanical properties including yield strength, tensile strength and thermal stress resistance were calculated from thermal properties measured through thermal conductivity and thermal expansion coefficient.

Low temperature cofired ceramics (LTCC) is a multilayer substrate manufacture technology which demands certain characteristic dielectric material to provide advantageous outcomes in the high frequency application unlike other technology. In view of that some doped niobates viz. CuxMg1-xNb2O6 (x=0,0.2,0.4,0.6,0.8,1) and CaxMg1-xNb2O6 (x=0,0.2,0.4,0.6,0.8,1) columbites have been prepared using sol-gel technique. The samples were sintered at 900 degrees C for 6 hours. Structural characterization of the prepared samples has been done using X-ray diffraction (XRD) method. Microwave dielectric properties like dielectric constant, Qf values and tau(f) values over Ku-band for all the compositions have been measured using a network analyser. It has been found out that doping effects change in properties significantly as a concurrence of structural ordering change and this ensures the suitability towards LTCC applications. Moreover, the low dielectric loss of these materials has shown an advantage. More »»

LTCC (Low Temperature Co-fired Ceramics) being the most advantageous technology towards the multilayer substrates for various applications, demands an extensive study of its raw materials. In the present work, a series of CuxMg1-xNb2O6 (x=0,0.4,0.6,1) has been prepared using sol-gel synthesis route and sintered at a temperature of 900°C to study its applicability for LTCC technology as the firing temperature is 900°C in this technology. The phase formation has been confirmed using X-ray Diffraction. Thermal properties like thermal conductivity and thermal expansion being very important aspect as the former defines the heat flow to avoid thermal instability in layers and the later provides the dimensional congruency of the dielectric material and the conductors, are studied here over high temperature up to the firing temperature. Although the values are quite satisfactory from substrate requirement point view, results have shown anomaly over temperature. The anomalous thermal behavior has been further analyzed using TGDTA.

Low temperature co-fired ceramics (LTCC), being the most advantageous technology related to the multilayer substrates for various applications, demands an extensive study of raw materials. In the present work, a series of CaxMg1−xNb2O6 (x =0, 0.4, 0.6, 1.0) were prepared using sol-gel synthesis route and sintered at a temperature of 900°C to study its applicability for LTCC technology. The phase formation has been confirmed using X-ray diffraction. Thermal properties like thermal conductivity and thermal expansion, which are very important aspects as the former defines the heat flow to avoid thermal instability in the layers and the latter provides the dimensional congruency of the dielectric material and the conductors, are studied here over high temperature range up to the firing temperature. Although the values are quite satisfactory from the application point view, the results have showed an anomaly over temperature. The anomalous thermal behavior was further analyzed using TG-DTA.

To study their applicability in low temperature cofired ceramic (LTCC) technology, dielectric and thermal properties have been characterized. Microwave dielectric properties like dielectric constant and Qf values over Ku-band for all the compositions have been measured. Dielectric constant was found to fall between 4.8 to 10. Thermal properties like thermal conductivity and thermal coefficient of expansion (TCE) were measured over a temperature range from room temperature to 900 0C. Thermal conductivity was found to be of the order of 1-2 W/m 0K while TCE was of the order of 5-10 x 10-6/0C. TCE of some of the compositions have shown negative value at 900 0C. More »»
