This three-hour lesson describes the impacts of weather on aviation operations and highlights the role of the National Weather Service (NWS) in supporting the Federal Aviation Administration's air traffic management organization. The lesson contains an Introduction (40 min), several cases (10-20 min each) focused on various weather phenomena, and a detailed case (35 min) allowing forecasters to follow the planning for and evolution of an event. The content emphasizes best practices for aviation forecasters, including identifying and communicating the threat, understanding partners' needs, and ...GOES-R ABI: Next Generation Satellite Imaging
This extension of the COMET lesson “GOES-R: Benefits of Next Generation Environmental Monitoring” focuses on the ABI instrument, the satellite's 16-channel imager. With increased spectral coverage, greater spatial resolution, more frequent imaging, and improved image pixel geolocation and radiometric performance, the ABI will bring significant advancements to forecasting, numerical weather prediction, and climate and environmental monitoring. The first part of the lesson introduces the ABI's key features and improvements over earlier GOES imagers. The second section lets users interactively ex ...Arctic Meteorology and Oceanography
Diminishing sea ice has opened the Arctic to navigation and operations like never before. Forecasters are increasingly predicting weather in support of those operations. This module is intended to provide forecasters with a brief introduction to the Arctic, including its geography, climatology, and the forecast problems they are likely to encounter. The module follows a U.S. Coast Guard Cutter on a voyage from Dutch Harbor, in the Aleutian Islands, to Barrow, on the north coast of Alaska. Various topics are addressed along the way in a series of short, stand-alone lessons.Remote Sensing Using Satellites, 2nd Edition
The second edition of the popular "Remote Sensing Using Satellites" module updates imagery of recent hurricanes as well as other phenomena from more recent satellites. The suggested audience for this module is high school and undergraduate students. Learn about remote sensing in general and then more specifically about how it is done from satellites. We will focus on the visible and infrared channels, those commonly seen on television broadcasts. Come explore the view of Earth from space and see what we see. In the second chapter, we will focus even more on hurricanes and specifically Hurrican ...Satellite Meteorology: GOES Channel Selection V2
This module is an update to the previous Satellite Meteorology: GOES Channel Selection module. It reviews the five GOES imager channels and their use, incorporating conceptual visualizations and numerous imagery examples. The module also includes updated information on improvements for the GOES-13, -14 and -15 satellites. Highlights include a higher resolution 13.3 micrometer CO2 channel (GOES-14 & -15), modified spectral response of the visible channel, improved radiometric performance and pixel geolocation, and shortened data outages during the fall and spring satellite eclipse periods.Role of the Skywarn Spotter
The goal of the "Role of the SKYWARN® Spotter" module is to provide baseline training for all spotters through multiple scenarios covering the procedures for spotting (including communication and storm report criteria), safety considerations for all hazards, and an overview of the national program and its history.Writing TAFS for Ceilings and Visibility
"Writing TAFs for Ceilings and Visibility" is the fifth unit in the Distance Learning Aviation Course 2 (DLAC2) series on producing TAFs that meet the needs of the aviation community. In addition to providing information about tools for diagnosing low ceilings and reduced in visibility and its related impacts, the module extends the Practically Perfect TAF (PPTAF) process to address an airport's operational thresholds. By understanding the thresholds at airports for which they produce TAFs, forecasters will be better able to produce a PPTAF. The unit also examines how to communicate effectivel ...Fog: Its Processes and Impacts to Aviation and Aviation Forecasting
This module first introduces forecasters to aviation-forecast customers and their needs, and discusses how fog impacts aviation operations. The main content of the module then explains the physical processes and life cycle of radiation and advection fog, including their preconditioning environment, initiation, growth, and dissipation. The processes covered in the module include radiation (both solar and longwave), soil-atmosphere thermal interactions, turbulent mixing, the roles of condensation nuclei, and droplet settling. Each section of the module includes a set of interactive questions bas ...BoM Aviation Fog Case Exercise
This case exercise focuses on a potential fog event in Melbourne, Australia, on 6-7 April 2008. The key aim of this module is to step through the forecast process during a potential fog event from the perspective of an aviation forecaster with the Australian Bureau of Meteorology. This involves consideration of model guidance and observations, identification of potential areas of fog, forecasting and nowcasting fog formation and clearance, and considering and providing TAF updates throughout.Fourth International Conference on fog, fog collection and dew - program and abstracts
World Meteorological Organization (WMO) ; Instituto de Geografía Universidad Católica de Chile; Atacama Desert Center (ADC); et al. - Universidad Católica de Chile, 2009GOES-R: Benefits of Next-Generation Environmental Monitoring
This module is an introduction to NOAA's next generation Geostationary Operational Environmental Satellite-R (GOES-R) series, focusing on the value and anticipated benefits derived from an enhanced suite of instruments for improved monitoring of meteorological, environmental, climate, and space weather phenomena and related hazards. An extensive set of visualizations highlight GOES-R and its advanced observing capabilities for providing support in thirteen key environmental application areas including air quality and visibility, climate, cloud icing, fires, hurricanes, land cover, lightning, l ...Dynamically Forced Fog
Fog frequently forms in response to dynamically forced changes in the boundary layer. This module examines dynamically forced fog in the coastal and marine environment, focusing on advection fog, steam fog, and west coast type fog. The focus of the module is on the boundary layer evolution of air parcels as they traverse trajectories over land and water. The module also examines mesoscale effects that impact the distribution of fog and low-level stratus over short distances. A general discussion of forecast products and methodologies concludes the module.Applying Diagnostic and Forecast Tools: Forecasting Fog and Low Stratus
This module discusses how to apply various observational data and remote sensing tools such as satellite, METARS, soundings, profilers, radar, and model analyses to diagnose the potential for fog and/or low stratus. Various forecast tools (such as model forecast fields, forecast soundings, and BUFKIT) used to assess fog and/or low stratus potential onset, intensity, and duration are also examined. This module is part of the Distance Learning Course 1: Forecasting Fog and Low Stratus.Writing Effective TAFs
This module provides an overview of some of the applicable TAF Amendment and Conditional Group usage rules, as presented in the latest version of the National Weather Service Instruction 10-813 on TAF directives. It also presents a methodology for TAF writing and development that will lead to an effective and user-friendly product. The focus is on the ceiling and visibility aspects of the TAF. This module is part of the Distance Learning Course 1: Forecasting Fog and Low Stratus.Synoptic Weather Considerations: Forecasting Fog and Low Stratus
In order to assess whether a fog or stratus event is possible, you must evaluate the synoptic-scale influences that will drive the local conditions. In this module, we examine several common synoptic situations to understand the processes involved in fog or low stratus development. Most of these are forced primarily by advective or dynamic processes (although radiation does play a role). A more detailed discussion of radiation processes is contained in the Radiation Fog module. This module is part of the Distance Learning Course 1: Forecasting Fog and Low Stratus.
