The Queen's absence at the Remembrance Sunday service on November 14 comes after she canceled several royal engagements amid health concerns. The Rams knew Von Miller had an ankle injury when they acquired him but it was worse than suspected, according to Adam Schefter.
The Real Housewives of Atlanta alum sizzled in not one, but three teeny string bikinis during her dreamy beach vacation. Porsha started off her trip with a head-turning neon ensemble, rocking a bright orange string bikini. The eye-catching swimsuit featured a halter top and low-rise bottoms with ties at each side.
She topped off the barely-there two-piece with a vibran. It was the midfield that dominated, for a change. Close this content. Read full article. September 23, , PM.

The precise reentry time and location of debris impacts have not been determined. The spacecraft likely broke apart and landed in the Pacific Ocean far off the U.
The spacecraft will eventually burn up in the atmosphere. The observations by the other four instruments were captured only in real-time by using the TDRS. It was hoped that UARS would continue operations through the summer of UARS carries ten complementary experiments, each experiment providing measurements critical to our understanding of processes in the upper atmosphere. The UARS orbit provides about 60 minutes of sunlight in each orbit of which about 35 minutes are available for solar viewing.
CLAES measures concentrations of members of the nitrogen and chlorine families, as well as ozone, water vapor, methane, and carbon dioxide. To obtain a vertical profile of species concentration, CLAES utilizes a telescope, a spectrometer, and a linear array of 20 detectors to make simultaneous measurements at 20 altitudes ranging from 10 to 60 km.
Because the detectors and optics generate their own thermal emissions, they must be cooled to temperatures which suppress this emission. CLAES had a mass of 1, kg with dimension of about 1.
It produced a month global database showing the vertical distributions of important ozone-layer gases in the stratosphere and their variation with time of day, season, latitude, and longitude.
Taylor, Oxford University, UK. This is a SAMS Stratospheric and Mesospheric Sounder instrument successor using filter radiometry and pressure modulation techniques in the following ranges: 4. ISAMS is a filter radiometer employing eight detectors. It observes infrared molecular emissions by means of a movable off-axis reflecting telescope.
In addition to scanning the atmosphere vertically, the telescope can also be commanded to view regions to either side of the UARS observatory, thus providing increased geographic coverage. One feature of ISAMS is that it carries samples of some of the gases to be measured in cells within the instrument. Atmospheric radiation collected by the telescope passes through these cells on its way to the detectors spectra matching.
The limb-sounding instrument, ISAMS, uses a combination of pressure-modulated and wide-band infrared channels to measure the concentrations of nitrogen chemical species, as well as ozone, water vapor, methane, and carbon monoxide in the middle atmosphere. Data rate: 1. Status: the ISAMS instrument experienced a chopper motor failure in late July , preventing its collection of atmospheric chemistry data.
Waters, JPL is a microwave radiometer which measures atmospheric thermal emission from selected molecular lines at mm wavelengths. Three-channel heterodyne limb sounder. Each band is MHz wide. MLS is a microwave radiometer providing global measurements of chlorine monoxide key reactant that destroys ozone , hydrogen peroxide, water vapor, and ozone. The MLS observations will provide, for the first time, a global data set on chlorine monoxide in the upper atmosphere.
MLS also determines the altitudes of atmospheric pressure levels. The overall instrument mass is kg, power consumption is W max , data rate: 1. The MLS instrument has three assembly units: spectrometer, power supply, and the main sensor.
The sensor includes the scanning antenna, the radiometer box, multiplexing optics, and the calibration system. The antenna subsystem is a dual-offset Cassegrain consisting of three elliptical reflectors. The primary reflector is an offset paraboloid, 1.
The secondary reflector is hyperboloid with dimensions 0. The antenna is scanned in the vertical in discreet steps from about 5 km to 95 km, every measurement cycle has a length of There are three radiometers in spectral bands centered at 63, and GHz.
The GHz radiometer is basically the same as the GHz radiometer. The GHz radiometer measures the signal from the water vapor and ozone bands. The 63 GHz radiometer is a space-qualified commercial mixer- amplifier module using a pair of Schottky barrier diodes. The GHz radiometer measures oxygen to determine atmospheric temperature. The optical multiplexer separates the radiation from the switching mirror into the three radiometers. The 63 GHz beam is separated with a dichroic plate consisting of equally spaced circular holes in a metal plate.
The and GHz beams are separated by a polarization grid of finely spaced wires. Calibration: radiometric views of cold space, and an on-board ambient-temperature blackbody target. The MLS onboard calibrations are performed by allowing the switching mirror to direct the radiometer FOVs to view both cold space and an internal ambient blackbody calibration target during each limb scan.
PI: J. The experiment employs the sun occultation technique by using a gas filter radiometer. Measurement of the vertical distribution of hydrofluoric and hydrochloric acids as well as of methane, carbon dioxide, ozone, water vapor, and members of the nitrogen family. The HALOE experiment uses samples of the gases to be observed as absorbing filters in front of the detectors to obtain a high degree of spectral resolution. The PEA links the instrument with the spacecraft.
The Sensor Assembly makes the science measurements and consists of eight science detectors and radiometers, a Cassegrain telescope, a two-axis gimbal assembly, a Sun sensor, the spacecraft adapter and supporting electronics.
The Cassegrain telescope reflects solar energy through a series of beamsplitters and spectral filters to the photovoltaic detectors for the gas filter correlation channels and to the broadband filter radiometer channels. The atmospheric target gases are detected at specific wavelengths between 2. It came with a warning of a slow load time and yes, it took forever to load. My patience was rewarded as the page finally appeared and featured a link to see where UARS was right now.
