The Sun, The Earth, and Near-Earth Space
While solar radiation enables and sustains life on Earth, it also produces “space weather” that can profoundly impact different technologies, including telecommunications, satellite navigation, and the electric power grid. Solar flares can produce x-rays resulting in radio blackouts that block high-frequency radio waves. Solar Energetic Particles can penetrate satellite electronics and cause electrical failure. Coronal mass ejections (CMEs) can cause geomagnetic storms that induce ground currents and degrade power grid operations, sometimes catastrophically. The Sun, The Earth, and Near-Earth ...

Coronal mass ejections (CMEs) can cause geomagnetic storms that induce ground currents and degrade power grid operations, sometimes catastrophically. The Sun, The Earth, and Near-Earth Space assembles concise explanations and descriptions—easily read and readily understood—of what we now know of the chain of events and processes that connect the Sun to the Earth, with especial emphasis on space weather and Sun-Climate.

SatFC-J: The VIIRS Day/Night Band
This lesson introduces the innovative Day/Night Band (DNB). Producing both daytime and nighttime visible images, the unique aspect of the DNB is its nocturnal low-light imaging capability. It views reflected moonlight from clouds and Earth's surface, surface light emissions from various natural sources (such as fires) and anthropogenic sources (such as city lights and gas flares), and even from certain atmospheric light emissions such as the aurora, airglow, and lightning flashes. The lesson describes the capabilities and benefits of the DNB, in particular using the Near-Constant Contrast (NCC ...

The lesson describes the capabilities and benefits of the DNB, in particular using the Near-Constant Contrast (NCC) product, available in the NWS' AWIPS-2 (Advanced Weather Interactive Processing System). It also explores key features that can be seen in DNB imagery throughout the lunar cycle, and some practical uses of this imagery. This lesson is part of the Satellite Foundational Course for JPSS (SatFC-J).

Advances in Space-Based Nighttime Visible Observation, 2nd Edition
This updated one-hour lesson explores the types of atmospheric and surface features that can be observed at night. It describes recent technical improvements in nighttime visible imaging with the VIIRS Day/Night Band on board the Suomi NPP and JPSS satellites, and the lunar phases and other conditions necessary for effective nighttime visible imaging. This lays the foundation for the rest of the lesson, which explores operational uses of nighttime visible observations. These include the detection and monitoring of city lights, tropical cyclones, fog and stratus, polar nights, auroras, fires an ...

These include the detection and monitoring of city lights, tropical cyclones, fog and stratus, polar nights, auroras, fires and smoke, volcanic eruptions, dust storms, air pollution, moon glint, lightning, gas flares, ships and boats, and population/economic geography. The lesson is intended for weather forecasters and other environmental scientists who use nighttime environmental data. Other users, such as those in the transportation industry and economists, may benefit from it as well.

Possible Impact of the Boreal Spring Antarctic Oscillation on the North American Summer Monsoon
This study examined the relationship between the boreal spring (April-May) Antarctic Oscillation (AAO) and the North American summer monsoon (NASM) (July-September) for the period of 1979-2008. The results show that these two systems are closely related. When the spring AAO was stronger than normal, the NASM tended to be weaker, and there was less rainfall over the monsoon region. The opposite NASM situation corresponded to a weaker spring AAO. Further analysis explored the possible mechanism for the delayed impact of the boreal spring AAO on the NASM. It was found that the tropical Atlantic s ...

in Atmospheric and Oceanic Science Letters > Volume 3 Number 4 (16 July 2010) . - p.232-236This study examined the relationship between the boreal spring (April-May) Antarctic Oscillation (AAO) and the North American summer monsoon (NASM) (July-September) for the period of 1979-2008. The results show that these two systems are closely related. When the spring AAO was stronger than normal, the NASM tended to be weaker, and there was less rainfall over the monsoon region. The opposite NASM situation corresponded to a weaker spring AAO. Further analysis explored the possible mechanism for the delayed impact of the boreal spring AAO on the NASM. It was found that the tropical Atlantic sea surface temperature (SST) plays an important role in the connection between the two phenomena. The variability of the boreal spring AAO can produce anomalous SSTs over the tropical Atlantic. These SST anomalies can persist from spring to summer and can influence the Bermuda High, affecting water vapor transportation to the monsoon region. Through these processes, the boreal spring AAO exerts a significantly delayed impact on the amount of NASM precipitation. Thus, information about the boreal spring AAO is valuable for the prediction of the NASM.

SP, 05. The potential role of WMO in Space Weather : a report on the potential scope, cost and benefit of a wmo activity in support of International coordination of space weather services, prepared for the sixtieth executive council
The present report addresses the possible scope, cost and benefit of initiating a WMO activity in the area of Space Weather. The expression Space Weather is used to designate processes occurring on the Sun, in the magnetosphere, ionosphere and thermosphere, which have the potential to affect the near-Earth environment. These processes occurring mainly outside of the atmosphere are not meteorological phenomena, and thus haven’t so far been considered within the mandate of WMO. However, because of their importance and possible synergy with activities under WMO’s responsibility, the issue o ...

Space Weather Basics, 2nd Edition
This lesson presents an overview of space weather processes, their impacts on Earth and human activities, and the technologies used for forecasting space weather events. The lesson goal is to provide NWS forecasters a basic understanding of space weather and the operations of NOAA's Space Weather Prediction Center (SWPC). It will be of interest to a general audience as well.
