JPSS River Ice and Flood Products
This lesson introduces hydrologists, meteorologists, and the education community to two new JPSS (Joint Polar Satellite System) satellite capabilities for monitoring river ice and flooding. It begins by describing the need for information on river ice and flooding, the capabilities of the Suomi NPP and future JPSS VIIRS imagers to provide products for monitoring river conditions, and the new river ice and flood products. This is followed by several cases, notably the May 2013 Galena, AK flood event, that demonstrate the use and value of the products in monitoring river ice and related flooding ...
Advanced Himawari Imager (AHI): What’s Different from the GOES-R Advanced Baseline Imager (ABI)
This brief lesson provides an overview of the AHI on Himawari and highlights its differences from the GOES-R Advanced Baseline Imager (ABI). It discusses AHI’s improved capabilities in spectral coverage, spatial resolution, and imaging interval over the MTSAT-2 imager; the differences in spectral coverage and scan strategy between AHI and ABI and the impact on products; and how AHI data and products benefit forecasters in Alaska, Pacific Region, and CONUS. Note that the lesson complements COMET’s GOES-R ABI lesson, which should be taken before going through this lesson.
Flash Flood Processes
According to NOAA’s National Weather Service, a flash flood is a life-threatening flood that begins within 6 hours--and often within 3 hours--of a causative event. That causative event can be intense rainfall, the failure of a dam, levee, or other structure that is impounding water, or the sudden rise of water level associated with river ice jams. The “Flash Flood Processes” module offers an introduction to the distinguishing features of flash floods, the underlying hydrologic influences and the use of flash flood guidance (FFG) products. Through use of rich illustrations, animations, and inte ...
NCAR Climate Data Guide
The Climate Data Guide provides concise and reliable information on the strengths and limitations of the key observational data sets, tools and methods used to evaluate Earth system models and to understand the climate system. Citable expert commentaries are authored by experienced data users and developers, enabling scientists to multiply the impacts of their work and the diverse user community to access and understand the essential data. This resource is made available courtesy of NCAR's Climate and Global Dynamics Division and is not produced, owned or hosted by UCAR/COMET.
Instrumentation and Measurement of Atmospheric Temperature
This lesson offers a comprehensive overview of temperature measurement as related to the atmosphere, bodies of water, soils, and other parts of Earth’s surface. The lesson begins by defining temperature and why it is an important property to characterize. It provides details about the properties and characteristics of sensors used for temperature measurements and the advantages and disadvantages of different sensors depending on the application. Lastly, the lesson outlines the methods used for measuring different types of temperature, from soil to the free atmosphere.
Preparing to Evaluate NWP Models
This lesson prepares the forecaster to evaluate NWP analyses and forecasts using physically based conceptual models of the atmosphere, and the "Vertical Phenomenon Analysis Funnel". This funnel divides the atmosphere into three sections: lower stratosphere and tropopause, mid-to-upper troposphere, and lower troposphere. We discuss tools to use and atmospheric features to assess for each section of the atmosphere, using interactive case examples, and summarize the methodology with a comprehensive example. Finally, we compare model capabilities and the time and space scales of assessment tools u ...
Local Influences on Fog and Low Stratus
Local and mesoscale influences can make or break your fog or stratus forecast. Influences of local water bodies, terrain, vegetation, soil characteristics, and coastal features on the lower atmosphere can play a vital role in the development, duration, and intensity of these events. As part of the Distance Learning Course 1: Forecasting Fog and Low Stratus, this module examines several of these influences and discusses how they enhance or inhibit a fog or stratus event.
Satellite Monitoring of Atmospheric Composition
Satellite monitoring of atmospheric composition provides important information for a number of applications, including stratospheric ozone monitoring, long-range pollutant transport, biomass burning, air quality monitoring and forecasting, and climate change. This module provides an overview of the use of satellites in these application areas, the measurement techniques used, and the development of related operational services. In addition, the module covers a short history of European and U.S. satellite missions, as well as a look at future missions planned for monitoring atmospheric composit ...
Forecasting Heavy Rains and Landslides in Eastern Africa
Good rainfall draws many people to settle across the eastern Africa highlands for farming and other businesses. However, factors such as steep terrain, logging, livestock grazing, agriculture, and construction, have increased erosion and contributed to less stable slopes. These factors can lead to devastating landslides and mudslides, especially during episodes of very heavy rain. Forecasting and monitoring heavy rainfall is challenging, especially in mountainous regions that have few surface observations. This make satellite data critical for meteorologists and hydrologists forecasting for th ...
The Impact of Weather on Air Traffic Management
This module focuses on the National Airspace System (NAS) and how weather affects it. It describes the various components of the Federal Aviation Administration (FAA), how that organization manages air traffic, and how CWSU and WFO forecasts help the FAA's decision-making process. The module also provides tips on establishing a good professional relationship with this important partner (FAA), understanding their language, and preparing weather briefings that will give them the information they need. This module is part of a larger exercise to develop a station Weather Impacts Playbook, a suppl ...
Web-Based Ensemble Tools: Ensemble Situational Awareness Table
The National Weather Service (NWS) Western Region (WR) has developed a Ensemble Situational Awareness Table (ESAT), which uses probabilistic NWP to bring attention to the potential for extreme events, especially in middle-range forecasts. The lesson, which is the first of two on the ESAT, describes the ESAT and how its data can be used to support assessment of extreme weather event forecasts. Additionally, statistical methods, including employment of reanalysis and NWP model climatologies (R-Climate and M-Climate, respectively) are described in reference to the products available in the ESAT.
Instrumentation and Measurement of Atmospheric Pressure
This lesson provides information about current science and technologies for measuring atmosphere pressure. The lesson begins by reviewing the key physical laws governing atmospheric pressure, including Dalton's Law of Partial Pressures. Then, it explores typical requirements and uncertainty parameters related to atmospheric pressure sensors and provides details about the components of pressure sensors, including fluidic, mechanical, and electronic transducers. The lesson is part of the Instrumentation and Measurement of Atmospheric Parameters course series.
Introduction to Tropical Meteorology, 2nd Edition, Chapter 1: Introduction
This chapter introduces learners to tropical meteorology including various methods of defining the tropics. An overview of energy balance and the global climate system is presented. The role of the tropics in the global energy and momentum balance is presented. Atmospheric structure of temperature and humidity are discussed in terms of latitudinal variability. Pressure ranges and scales of atmospheric motion in the tropics are reviewed. Seasonal and geographic distribution and the diurnal cycle of surface temperature and the influencing factors are examined in detail. Finally, we review tropic ...
In-depth Physics Lessons
This collection of four condensed physics lessons is offered as a companion to our Physics of the Aurora: Earth Systems learning module, and has been developed especially for use by university physics educators. The lesson topics are Charged Particle Motions, Magnetic Force, the Frozen-field Theorem, and Static Atmospheres. Each short, self-contained lesson can be accessed independently and includes interactive formula derivations, exercises, and open-ended questions suitable for classroom discussion or out-of-class assignments.
