  • Practical Design of An Automotive Tail Light

    An inexpensive automotive tail light is made from 5mm red light emitting diodes (LEDs). This chapter looks at 5mm red LEDs in surface mount, limiting the search to those with ratings of at least 8000 mcd. That will require about 20 devices. The chapter argues that the design issues with temperature compensation that are complex enough that one can just do the design with 15 LEDs. After the issues and costs are explained, the customer agrees to this, since that's what they wanted anyway. The chapter documents the desired size of the tail light, as well as the desired mean time to failure (MTTF). It also mentions load dump. There are two ways of surviving load dump. The common way for most automotive electronics is to clamp the voltage coming out of the surge protection. The other way of handling load dump is what one is doing with the circuitry.

  • Calibration of special sensor microwave imager/sounder (SSMIS) upper air brightness temperature measurements using a comprehensive radiative transfer model

    For purposes of completing the initial calibration and validation work for the Special Sensor Microwave Imager/Sounder (SSMIS) serial number 2 instrument, we have implemented a comprehensive radiative transfer model (RTM) in order to verify on-orbit upper air brightness temperature measurements for SSMIS channels 19–24. Rigorous computational treatment of the effects of the Earth's magnetic field on absorption by oxygen in the stratosphere and mesosphere provides us a solid baseline for comparison of theoretically based forward RTM calculations with the satellite observations. With the inclusion of flexibility in our model to account for departures from perfect instrument behavior, initial results provide us a reasonable measure of confidence that the agreement of our model with the observations should make the SSMIS-derived data products sufficiently reliable.

  • Microwave brightness temperature of cratered lunar surface and inversions of the physical temperature profile and thickness of regolith layer

    Based on the multichannel brightness temperature observations of Chinese Chang'E-1 lunar satellite, inversions of the physical temperature profile of the lunar regolith medium and its layer thickness are discussed. The correspondence of the brightness temperature distribution to the lunar topography is demonstrated and discussed, especially around lunar polar regions under poor solar illumination. As examples, in two areas, along the lunar equator and along the line of longitude 150°W, the physical temperature profile of regolith layer and its thickness are inverted using a three-layer model of thermal radiative transfer. The results which are based on some Apollo measurements are compared with an empirical formulation of the physical temperature as a function of latitude.

  • Detecting tropical cyclone water vapor transportation with the TRMM and advanced microwave sounding unit (AMSU)

    The AMSU-B data contain the vertical distribution of the retrieved water vapor from satellite brightness temperature. The tropical cyclone Matsa event in 2005 formed from the Northwest Pacific is analysed by combining the AMSU-B water vapor fields with the latent heat. Results show the combination the TRMM latent heating data in the heavy precipitation area around TC, we find heat release is one of the most important factors to impact TC intensity, especially to the long-life and land load TC. And there is a time delay between the low level water vapor convergence and the middle layer latent heat, which will improve the real-time forecast of tropical cyclones.

  • Combined use of spectral measurements: a promise for surface parameter retrieval

    The objective of this study is to underline the benefits of a combined use of different spectral measurements and models in the retrieval of surface parameters controlling the hydrological cycle. The authors developed a method aimed at integrating data from various satellites, in different spectral bands (visible, thermal infrared and microwave) along with models adapted to each band in a two step iterative optimization procedure. They first invert radiative transfer model in the visible to retrieve a set of surface parameters from AVHRR visible and near-infrared reflectances. In a second step, these parameters in conjunction with surface temperature derived from AVHRR lire used as input into a radiative transfer model in the microwave region to simulate brightness temperature in SSM/I 19.35 and 37 GHz channels. By minimizing the difference between observed and simulated brightness temperatures, a set of relationship between surface albedo and soil moisture, surface reflectance and vegetation water content are discussed.<<ETX>>

  • Estimating the uncertainty in passive-microwave rain-retrievals

    Current passive-microwave rain-retrieval methods are largely based on databases built off-line using cloud models. The vertical distribution of hydrometeors within the cloud has a large impact on upwelling brightness temperatures. Thus, a forward radiative transfer model can predict off-line the radiance associated with different rain scenarios. To estimate the rain from measured brightness temperatures, one simply looks for the rain scenario whose associated radiances are closest to the measurements. To understand the uncertainties in this process, the authors first study the dependence of the simulated brightness temperatures on different hydrometeor size distribution (DSD) models. They then analyze the marginal and joint distributions of the radiances observed by the Tropical Rainfall Measuring Mission satellite and of those in the databases used in the TRMM rain retrievals. They finally calculate the covariances of the rain profiles and brightness temperatures in the TRMM passive-microwave database and derive a simple parametric model for the conditional uncertainty, given measured radiances. These results are used to characterize the uncertainty inherent in the passive-microwave retrieval.

  • Land cover classification methods for multiyear AVHRR data

    AVHRR data have been extensively used for global land cover classification, but few studies have taken direct and full advantage of the multiyear properties of AVHRR data. The authors generated three types of signatures from 12-year monthly composite NDVI (normalized difference vegetation index) and channel 4 brightness temperature (T/sub 4/) of NOAA/NASA Pathfinder AVHRR Land data for land cover classification. Both quadrature discriminate analysis (QDA) and linear discriminate analysis (LDA) are explored for classification. A global land cover training database created from Landsat TM and MSS imagery is used for training and validation. It turns out that QDA performs much better than LDA, and the overall classification rate is as high as 95.9%.

  • Pre- Launch Radiometric Calibration System for the MetOp-SG MWS Instrument

    Accurate pre-launch calibration of the MetOp-SG (Meteorological-Operations Second-Generation) Microwave Sounder (MWS) remote sounding instrument is critical in achieving an operational radiometric temperature uncertainty of 0.1 K. The RAL Space department at the STFC Rutherford Appleton Laboratory is working with Airbus Defence and Space (UK) to a develop calibration system for MWS. This system sets a new level of required calibration accuracy for (sub-) millimetre wave space-borne instruments, and needs blackbody targets with a temperature stability of 0.05 K over 5 minutes and 0.5 K over 1 hour for the temperature range 80 K to 335 K, with a return loss requirement of 45 dB. Achieving the required target diameters of 0.5 m presents significant design and manufacturing challenges.
