Digital Library for Earth System Education (DLESE)
(26.580 recursos)
The Digital Library for Earth System Education (DLESE) is a grassroots, community-based effort involving teachers, students, and scientists working together to create a library of educational resources and services to support Earth system science education. DLESE supports Earth system science education by providing access to high-quality collections of educational resources; access to Earth data sets and imagery; support services to help educators and learners effectively create, use, and share educational resources; and communication networks to facilitate interactions and collaborations across all dimensions of Earth system education.

River Forecasting Case Study - Tim Spangler
This module takes the learner through the considerations for the river forecasting decisions associated with the remnants of Hurricane Ivan on 17-19 September, 2004 for the Susquehanna River system in Pennsylvania and New York. The module assists the learner with applying the concepts covered in the foundation topics of the Basic Hydrologic Sciences course. Some of the specific topics pertinent to this case are soil conditions, the impact of QPF on runoff, runoff models, runoff processes, routed flow and stage-discharge relationships. Observations of upstream conditions and comparisons to historic crests are also examined to assist with operational flood forecast decisions....

Microwave Remote Sensing Resources - Tim Spangler
This module provides background information on microwave remote sensing with polar-orbiting satellites. It reviews coverage, orbits, and data latency issues of current operational and selected research satellites and notes improvements expected in the NPP and NPOESS era. The module contrasts active vs. passive remote sensing, discusses advantages and limitations of different microwave instrument scanning strategies, and addresses viewing geometry with implications for spatial resolution and swath coverage. Finally, it offers a review of the microwave spectrum and special characteristics of microwave energy important for understanding microwave imagery and derived products. This module takes about 1 hour to complete. Educational levels:...
