This book was released on 2019-01-16 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method for estimating the integrated precipitable water (IPW) content of the atmosphere using measurements of indicated infrared zenith sky temperature was validated over east-central Florida. The method uses inexpensive, commercial off the shelf, hand-held infrared thermometers (IRT). Two such IRTs were obtained from a commercial vendor, calibrated against several laboratory reference sources at KSC, and used to make IR zenith sky temperature measurements in the vicinity of KSC and Cape Canaveral Air Force Station (CCAFS). The calibration and comparison data showed that these inexpensive IRTs provided reliable, stable IR temperature measurements that were well correlated with the NOAA IPW observations.

Available in PDF, EPUB and Kindle. Book excerpt: Maverick Scientist is the memoir of Forrest Mims, who forged a distinguished scientific career despite having no academic training in science. Named one of the "50 Best Brains in Science" by Discover magazine, Forrest shares what sparked his childhood curiosity and relates a lifetime of improbable, dramatic, and occasionally outright dangerous experiences in the world of science. At thirteen he invented a new method of rocket control. At seventeen he designed and built an analog computer that could translate Russian into English and that the Smithsonian collected as an example of an early hobby computer. While majoring in government at Texas A&M University, Forrest created a hand-held, radar-like device to help guide the blind. And during his military service, he had to be given special clearance to do top secret laser research at the Air Force Weapons Lab. Why? Because while he lacked the required engineering degree, they wanted his outside-the-box thinking on the project. He went on to co-found MITS, Inc., producer of the first commercially successful personal computer, wrote a series of electronics books for Radio Shack that sold more than seven million copies, and designed the music synthesizer circuit that became known as the infamous Atari Punk Console. All this came before he started consulting for NASA's Goddard Space Flight Center, and NOAA's famous Mauna Loa Observatory, and earning the prestigious Rolex Award. This intimate portrait of a self-made scientist shares a revelatory look inside the scientific community, and tells the story of a lifelong learner who stood by his convictions even when pressured by the establishment to get in line with conventional wisdom. With dozens of personal photos and illustrations, Maverick Scientist serves as proof that to be a scientist, you simply need to do science.

This book was released on 1976 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiance values for the eight water vapor channels on the DMSP/SSH infrared sounder were simulated for cloud free conditions. The simulated values were inverted using a statistical multiple regression procedure to estimate total precipitable water. Inversions were also obtained using both the infrared water vapor channel data and temperature profile data. For the sounder channels incorporated into the DMSP/SSH sensor package, profile measurements are not possible below the height of the tropopause using the infrared channel data alone. Successful inversions with more than an 80 percent reduction of variance from climatological values were accomplished using both temperature profile data (perhaps obtained from the CO2 channel data) and one or more infrared water vapor channel observations.

Download or read book Solar and Infrared Radiation Measurements Second Edition written by Frank Vignola and published by CRC Press. This book was released on 2019-07-30 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rather specialized field of solar and infrared radiation measurements has become increasingly important due to the increased demands by the renewable energy and climate change research communities for data with higher accuracy and increased temporal and spatial resolutions. Recent advances in radiometry, measurement systems, and information dissemination also have increased the need for refreshing the literature available for this topic. This book provides the reader with an up-to-date review of the important aspects of solar and infrared radiation measurements: radiometer design; equipment installation, operation, maintenance, and calibration; data quality assessment parameters; and the knowledge necessary to properly interpret and apply the measured data to a variety of topics. Each of the authors has more than 40 years of experience with this subject, primarily as the result of developing and operating multiple measurement stations, working with the industry to improve radiometry, and conducting various research projects. The book’s scope and subject matter have been designed to help a wide audience gain a general understanding of this subject and to serve as a technical reference. A student new to the field will benefit from the review of terminology and the historical perspective for radiometry before addressing more detailed topics in radiometry that we hope will be of interest to the more experienced reader.  Describes the strengths and weaknesses of irradiance instruments  Provides detailed information on how to assess uncertainty in measurements  Offers comprehensive background information needed to understand the use of solar instrumentation  Discusses design concepts for shadowband radiometers, sky imagers, and satellite-based estimates of solar irradiance at the Earth’s surface  Includes chapter-end questions, references, and useful links

Download or read book Atmospheric Pre corrected Differential Absorption Techniques to Retrieve Columnar Water Vapor written by and published by . This book was released on 1996 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water vapor is one of the main forces for weather development as well as for mesoscale air transport processes. The monitoring of water vapor is therefore an important aim in remote sensing of the atmosphere. Current operational systems for water vapor detection use primarily the emission in the thermal infrared (AVHRR, GOES, ATSR, Meteosat) or in the microwave radiation bands (DMSP). The disadvantage of current satellite systems is either a coarse spatial (horizontal) resolution ranging from one to tens of kilometers or a limited insight into the lower atmosphere. Imaging spectrometry on the other hand measures total column water vapor contents at a high spatial horizontal resolution and has therefore the potential of filling these gaps. The sensors of the AVIRIS instrument are capable of acquiring hyperspectral data in 224 bands located in the visible and near infrared at 10 run resolution. This data includes information on constituents of the earth's surface as well as of the atmosphere. The optical measurement of water vapor can be performed using sensor channels located in bands or lines of the absorption spectrum. The AVIRIS sensor has been used to retrieve water vapor and with less accuracy carbon dioxide, oxygen and ozone. To retrieve the water vapor amount, the so called differential absorption technique has been applied. The goal of this technique is to eliminate background factors by taking a ratio between channels within the absorption band and others besides the band. Various rationing methods on the basis of different channels and calculation techniques were developed. The influence of a trace gas of interest on the radiance at the sensor level is usually simulated by using radiative transfer codes. In this study, spectral transmittance and radiance are calculated by MODTRAN3 simulations with the new DISORT option. This work testS the best performing differential absorption techniques for imaging spectrometry of tropospheric water vapor.
