Book Synopsis Global Water Vapor Estimates from Measurements from Active GPS RO Sensors and Passive Infrared and Microwave Sounders by : Shu-Peng Ho

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water vapor plays an important role in both climate change processes and atmospheric chemistry and photochemistry. Global water vapor vertical profile can be derived from satellite infrared and microwave sounders. However, no single remote sensing technique is capable of completely fulfilling the needs for numerical weather prediction, chemistry, and climate studies in terms of vertical resolution, spatial and temporal coverage, and accuracy. In addition to the passive infrared and microwave sounder observations, the active global positioning system (GPS) radio occultation (RO) technique can also provide all-weather temperature and moisture profiles. In this chapter, we describe the current developments of global water vapor vertical profile and total precipitable water derived from active GPS RO measurements. In addition, we also demonstrate the potential improvement of global water vapor estimates using combined active GPS RO and passive IR/MW particularly from Atmospheric InfraRed Sounder (AIRS) and Advanced Technology Microwave Sounder (ATMS) measurements. Results show that because RO data are very sensitive to water vapor variation in the moisture rich troposphere, the RO data are able to provide extra water vapor information for the combined AIRS/ATMS and RO retrievals in the lower troposphere.

Available in PDF, EPUB and Kindle. Book excerpt: This handbook covers the air quality/air pollution from the viewpoints of causing impacts on human/ecosystem health and climate change. Traditionally, air pollution has been a concern mainly in terms of its impacts on human health, and it is still an immediate public and governmental concern in most Asian countries. However, in recent years so-called extreme weather events, such as stronger tropical cyclones, flooding, drought, and other phenomena, have been manifested causing tremendous losses of human lives and properties. Importantly, climate models tell us that such extreme weather events are actually induced by anthropogenic global warming. It has been pointed out that mitigation or alleviation of such climate change leading to the extreme weather events in the next 30 years can be possible only by reducing air pollutants with positive radiative forcing such as ozone or methane, which are called short-lived climate pollutants (SLCPs). Here, concerns about mitigation of air pollutants from the points of human health and climate change have merged. This book covers different kinds of air pollutants and radiative forcers and how they can be measured. It also mentions the situation of air pollutants in different continents and their regional impacts to human health, environment and economy as well as their link to extreme weather events. The book presents how the air pollution and climate change can be mitigated and how clean air technologies and international initiatives for co-controlling air pollution and climate change have been developed.

Book Synopsis Monitoring and Mitigation of Volcano Hazards by : Roberto Scarpa
Download or read book Monitoring and Mitigation of Volcano Hazards written by Roberto Scarpa and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 846 pages. Available in PDF, EPUB and Kindle. Book excerpt: By the year 2000, the number of people at risk from volcanic hazards is likely to increase to around half a billion. Since 1980, significant advances have been made in volcano monitoring, the data from which provides the sole scientific basis for eruption prediction. Here, internationally renowned and highly experienced specialists provide 25 comprehensive articles covering a wide range of related topics: monitoring techniques and data analysis; modelling of monitoring data and eruptive phenomena; volcanic hazards and risk assessment; and volcanic emergency management. Selected case histories of recent volcanic disasters, such as Mount Pinatubo in the Philippines, demonstrate that effective communication - between scientists, civil authorities, the media and the population at risk - is essential to reducing the danger.
Book Synopsis Water Vapor Variability Across Spatial Scales by : Kyle Gregory Pressel
Download or read book Water Vapor Variability Across Spatial Scales written by Kyle Gregory Pressel and published by . This book was released on 2012 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of this dissertation is the scale dependence of water vapor variability as observed by remote sensing and in situ measurements, and predicted by aqua-planet simulation. Global observations of the water vapor field from the Atmospheric Infrared Sounder (AIRS) are used to show that the first order structure function of the water vapor field exhibits power law behavior for scales between 50 km and 500 km throughout much of the troposphere. The power law scaling exponents are shown to vary between the boundary layer and free troposphere, with first order structure function scaling exponents of approximately 1/3 in the boundary layer and less than 1/2 in the free troposphere. Observations from the 396 m level of the WLEF television broadcast tower are used to show that the convective mixed layer layer and nocturnal residual layer exhibit power law behavior of first order structure functions and first order detrended fluctuation functions for scales between 1 km and 100 km. The power law scaling exponents computed from the tower observations of the convective mixed layer are shown to be consistent with the AIRS boundary layer regime exponents, while the exponents computed from the tower observations of the residual layer are shown to be consistent with AIRS free tropospheric regime scaling exponents. Finally, structure functions of the instantaneous water vapor field are computed from aqua-planet simulations performed at T85 and T340 spectral resolutions. Free tropospheric structure function scaling exponents for scales less than 500 km computed from the T340 spectral resolution simulation are shown to agree very well with free tropospheric scaling exponents computed from AIRS. Boundary layer structure function scaling exponents from the T340 spectral resolution are shown to be generally larger than boundary layer scaling exponents from AIRS.
Book Synopsis The Impacts of Convection on Upper-tropospheric and Lower-stratospheric Water Vapor by : Jing Feng
Download or read book The Impacts of Convection on Upper-tropospheric and Lower-stratospheric Water Vapor written by Jing Feng and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Upper-tropospheric and lower-stratospheric (UTLS) water vapor plays an essential role in controlling the outgoing longwave radiation. Convection can affect UTLS water vapor through cross-tropopause transport and by modulating the tropopause temperature. However, this mechanism remains poorly quantified due to a lack of observations above convective storms. In this thesis, we aim to understand the role of convection in shaping the UTLS humidity structure by developing a novel retrieval method.Firstly, we develop a cloud-assisted retrieval method to obtain thermodynamic fields above a thick cloud layer using hyperspectral infrared observations. Based on the Optimal Estimation approach, this method iteratively retrieves temperature and water vapor profiles above a thick cloud layer, which is approximated as a slab with uniform ice density. The retrievability of water vapor is examined by using simulations that represent different instrument settings. These experiments demonstrate that observations from operational infrared sounders, such as AIRS and IASI, contain considerable information for retrieving UTLS water vapor above thick clouds. Interestingly, we find that the underlying cloud layer improves the performance of the retrieval method, compared to clear-sky conditions. Using AIRS observations, further validation with collocated aircraft data shows that this method can detect the elevated water vapor concentration due to convective moistening.We further discover that the cloud properties near the top of convective clouds lead to non-negligible spectral uncertainties in infrared radiances. These uncertainties can be alleviated, but not fully eliminated, by assuming a slab-cloud as in the cloud-assisted retrieval. To overcome this issue, we develop a synergistic method, which incorporates observations from active sensors and nearest reanalysis products in synergy with hyperspectral infrared observations. The improved synergistic method retrieves temperature, water vapor, and cloud properties simultaneously. A simulation experiment is designed to investigate whether retrieval methods can capture anomalous atmospheric conditions above deep convective clouds using existing instruments. We find that the synergistic method reduces the root-mean-square-errors in temperature and column-integrated water vapor by more than half and accurately reproduces the spatial distribution of temperature and humidity anomalies above convective storms.Finally, we implement the improved method by combining infrared radiance observations from AIRS L1B product, ice water content (IWC) profile and effective radius from DARDAR-Cloud, and also atmospheric profiles from ERA5 in the nearest grid. Applying this method to satellite overpasses over tropical cyclones (TCs), we construct a dataset that contains retrieved temperature, humidity above TCs. With a focus on the tropical tropopause layer (TTL), the influence of tropical cyclones on the TTL is investigated by creating composites of temperature, humidity, IWC, and radiative heating rates with respect to the distance to the cyclone centers. We find that overshooting convective clouds (DCC-OTs) greatly impact the TTL water budget. DCC-OTs contribute to 80% of the TTL cloud ice above cyclones and increase the column-integrated water vapor above the tropopause by up to 40% compared to the climatology. Other non-overshooting TTL clouds are found to be collocated with TTL temperature minimum and dehydration. Overall, the synergistic retrieval reveals that cyclones increase the stratospheric humidity above them. However, further radiative transfer calculations show that the increased moisture is typically associated with radiative cooling of the TTL, which inhibits the diabatic ascent of the moistened air. Therefore, the radiative balance of the TTL under the impact of the cyclone is not in favor of maintaining the moist anomalies in the TTL or transporting water vertically to the stratosphere"--
