|
 | Observing system simulation experiments (OSSEs) are conducted to assess the impact of the Special Sensor Microwave 183 GHz (SSM/T-2) water vapor sounder and the associated SSM/T-1 temperature sounder. Analyzed and forecast meteorological fields are improved by the addition of the SSM/T-1,2 temperature and humidity profiles. The greatest impacts occur in the Southern Hemisphere in the scenario when the civilian infrared sounder data are not available, i.e., when TOVS data are ... |

 | The goal of this project has been to investigate the potential of antisense oligonucleotides to kill Leishmania enriettii cells in culture. These antisense oligonucleotides are directed against the 35-base leader sequence spliced to the 5'-end of all Leishmania mRNA, with the objective of achieving cell kill by arresting translation. Agents that successfully arrested growth or killed the parasites in vitro would be viable candidates for study in animal models for ... |

| The objective of the subject contract was to develop methodology for effectively using satellite altimetry for oceanographic applications. Another task was to examine techniques for measuring and monitoring rotating fluid phenomena. In addition, a task was added later by NORDA to develop ice motion techniques from sequential AVHRR imagery. The ice motion work involved the use of filtered cross correlation between relatively cloud free sequential AVHRR images to examine temporal ... |

G. A. White; AIR FORCE INST OF TECH WRIGHT-PATTERSON AFB OH
|
| There has been continual improvement in the accuracy of retrieved atmospheric soundings from satellite radiance measurements; however, satellite data still provide an overly smooth product which is of limited use for synoptic scale analysis. Considerable smoothing occurs when information present in satellite radiance measurements is lost in the retrieval process. This research describes and develops techniques which: (1) identify synoptic features and (2) quantify their fine structures directly from TIROS ... |

|
| The logistical significance of chemical weapons in future warfare demands that nerve agent antidotes be available for troops exposed to chemical attack. Since future combat operations will most likely occur in tropical and desert areas, chemical attacks in such areas could lead to situations involving the use of nerve agent antidotes by troops during exposure to hot and hot-humid conditions. Virtually no data are available to estimate performance capabilities on ... |

| The differential inversion method (DIM) is presented in the context of the fundamental principles governing the transfer of radiation for plane- parallel atmospheres in local thermodynamic equilibrium. In the Laplace inverse plane, the Planck intensity is linearly related to upwelling radiances weighted by the weighting function. By applying the inverse transform, the local Planck intensity can be exactly expressed by a linear combination of the derivatives of upwelling radiances in ... |

| A forward looking infrared device (FLIR) operating at 3.5-5 microns was tested for comparison against a previously tested FLIR operating at 9-12 microns. Results from both tests are used to compare operating ranges of the devices in the tropics. Theory suggests an increased detection and recognition range should be possible by using the mid infrared region. A low infrared profile, 110' Coast Guard patrol boat, served as a target for ... |

| Seasonal changes of mixed layer depth (MLD) can be related to the forcing by the net surface heating and wind speed. This is shown in this study by comparing the monthly mixed layer depth from temperature profiles in the Bauer-Robinson Numerical Atlas with monthly net surface heating and wind speed obtained from the Weare Marine Climatic Atlas of the Tropical Pacific Ocean. Using a conceptual model based on mixed layer ... |

|
| Planetary-scale equatorial waves play an important role in the dynamics of the tropical atmosphere. They are believed to be excited in unsteady convective heating in the tropical troposphere. From convective centers in the intertropical convergence zone (ITCZ), equatorial waves propagate vertically into the upper atmosphere where they are eventually absorbed, e.g., through radiative dissipation. A spectrum of vertically propagating Kelvin waves was revealed to be trapped about the equator, radiating ... |

| Dust storms are complex phenomena that are dependent on many meteorological and environmental factors. Because they normally occur in remote and in hospitable regions, they have been studied relatively little. Such studies are further hampered by the dearth of meteorological, climatological and geological data for such regions. In particular, the occurrence of the major storms seems to be related to identifiable meteorological conditions; such storms should be predictable with a ... |
