MetEd - Sea Ice and Products and Services of the National Ice Center

This two-hour module examines sea ice, icebergs, and the products and services of the National Ice Center and the North American Ice Service. Topics include climatology and current trends in sea ice extent and thickness; the development, classification, and drift of sea ice and icebergs; fractures, leads and polynyas; and the satellite detection of sea ice using visible, infrared, and microwave sensors.

Understanding the Hydrologic Cycle: International Edition

This module helps students gain a basic understanding of the elements of the hydrologic cycle. The hydrologic cycle is the continuous movement and phase change of liquid water, ice, and water vapor above, on, under and through the earth's surface. This module examines the basic concepts of the hydrologic cycle including water distribution, atmospheric water, surface water, groundwater, and snowpack/snowmelt.

The Klamath Basin Water Crisis

In this case study, students examine global water shortage problems in the context of the current Klamath Basin water crisis. Two main perspectives are addressed, agriculture and the environment, along with multiple other perspectives including Native Americans, hydroelectric dams, and the fishing industry. Students learn about and discuss competing interests for water and analyze and critique scientific data, maps, and graphs. The case was developed for a social sciences track environmental studies course. It could be used in an environmental science, ethics, or policy course as well as in water management or agriculture classes.

MetEd - 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 Hurricanes Jimena (2009), Ike (2008), and Irene (2011).

MetEd - Jason-2: Using Satellite Altimetry to Monitor the Ocean

Altimeters onboard satellites such as Jason-2 measure sea surface height and other characteristics of the ocean surface. These characteristics are linked to underlying processes and structures, making altimetry data useful for understanding the full depth of the global ocean. This 75-minute module explores major discoveries made possible by altimetry data in oceanography, marine meteorology, the marine geosciences, climate studies, the cryosphere, and hydrology. For example, altimeters have played a vital role in detecting and monitoring sea level rise and its relation to climate change. The module also describes many of the practical applications of altimetry data, for example, in hurricane forecasting and monitoring climate events such as ENSO. Finally, the module describes Jason-2, which was launched in 2008, its products and services, and the Ocean Surface Topography Mission (OSTM), of which it is a part. OSTM is a collaboration between EUMETSAT and CNES (Europe) and NOAA and NASA (United States).

MetEd - Monitoring the Climate System with Satellites

The international science community has identified a set of Essential Climate Variables (ECVs) that should be monitored for measuring the climate system, how it is changing, and its likely impact on future climate. Environmental satellites play an important role in this effort. They are uniquely positioned to provide broad, spatially consistent, and continuous global sampling of many of the ECVs.

This module explores the benefits of monitoring the climate system with satellites. We begin by reviewing how satellites observe key atmospheric elements and features that are found in a variety of climate cycles and are important for studying long-term climate trends. From there, we explore events at the different scales (from seasonal to long-term) and the contributions that satellites make to improving our understanding, monitoring, and prediction of them. Finally, we discuss the challenges involved in monitoring climate with satellites. Among these is the need for continuous, stable, high-resolution, and validated measurements that are coordinated with the world’s satellite operators.

MetEd - Introduction to Climatology

This module provides an overview of climatology, the study of climate. The module begins by examining the drivers that combine to create the climate regions of the world—from those at the mesoscale (local) level to those at the synoptic-scale (continental) and global-scale levels. Examples include locally dominant winds, air masses, fronts, ocean currents, Earth’s rotation around the sun, and latitude. Each discussion of a climate driver has an ‘example/exploration’ segment, where the information is applied to several cities. The module also examines a scheme for classifying the world’s climate zones, the sources and uses of climate information, and some of its limitations. The module is intended for a wide range of users, from forecasters and scientists to those in business and government as well as the general public—in short, anyone interested in learning about climatology. Some familiarity with basic meteorology is useful although not required.
