Glacial dust streams into the Gulf of Alaska

16th November 2017

Glacial Dust from the Copper River Valley

The NOAA/NASA Suomi NPP satellite’s VIIRS instrument captured this plume of glacial dust streaming into the Gulf of Alaska from the Copper River Valley. As glaciers flow, they grind against underlying bedrock, which produces a very fine powder known as “glacial flour” or “rock flour.” Rich in iron, this silty substance often flows into rivers and lakes, giving the water a brown or grey tinge. When water levels are low, the flour dries out on riverbanks and deltas. Winds then lift the dust into the air and can transport it over several hundred miles of open ocean. Researchers are using satellite data to better understand how glacial dust events in the Gulf of Alaska can trigger phytoplankton growth, which affects marine ecosystems in the region.

Although true-color images like this may appear to be photographs of Earth, they aren't. They are created by combining data from the three color channels on the VIIRS instrument sensitive to the red, green and blue (or RGB) wavelengths of light into one composite image. In addition, data from several other channels are often also included to cancel out or correct atmospheric interference that may blur parts of the image.

Heavy rain and snow battering the Pacific Northwest

14th November 2017
The storm system will deliver high winds and heavy rain

A strong low pressure system approaches the Pacific Northwest in this image from NOAA’s GOES-16 satellite, taken November 14, 2017. The storm system will deliver high winds and heavy rain to coastal areas, while heavy snow is expected across the mountain ranges of the Pacific Northwest and parts of the Sierra Nevada. The National Weather Service has issued winter storm warnings in high-elevation regions of the Pacific Northwest, and gale warnings are in effect along the Oregon and Washington coasts.

Created by our partners at the Cooperative Institute for Research in the Atmosphere, the experimental geocolor imagery enhancement displays geostationary satellite data in different ways depending on whether it is day or night. In daytime imagery (shown here), land and shallow-water features appear as they do in true-color imagery. Please note: GOES-16 data are currently experimental and under going testing and should not be used operationally. (Image and detail source:NOAA)

Flag March by Revolutionary Party of India (RMPI)

Centenary Celebration of Russian October Revolution

Ludhiana: 7th November 2017: (Punjab Screen Team)::

The Revolutionary Marxist Party of India (RMPI ) organised a flag march in the city today to commorate 100 years of Russian Revolution led by com. VI Lenin. This revolution left an indelible mark on whole world. It brought Russia to the status of a world super power ending poverty and unemployment . it paved the way for Quality Education Health and other basic needs for all its citizens. not only that Russia could help many countries to win freedom and embark upon the path of development. It also impressed thousands of thinkers intellectuals and revolutionaries like Shaheed Bhagat Singh who also set forth Socialism as a goal for India alongwith winning freedom from the British Imperialists.

        As a result of such sacrifices our country could win freedom in 1947 but the goal of Revolution ( Inqulab ) to a socialist India is still unfulfilled. The dispensations at the helm under both congress led UPA and BJP led NDA have been working to serve the interests of Indian and foreign MNC's thus forcing millions of workers peasants small traders and enterpreneurs to live a miserable life. The present capitalist path of development  has led to so called jobless growth thus leading to unprecedented groth of unemployment for the youth particularly the ones who got costly and unaffordable education. The only solution for India's problems is a socialist revolution. This was stated by com. Jagtar Singh district secretary RMPI  Com Raghbir Singh and Com Mohinder Singh Acharwal Amarjit Singh Sehzad Jamhoori Kissan Sabha leaders Harnek Singh Shaheed Bhagat Singh Naujwan Sabha Leader Com Charanjit Singh MNREGEA workers union leader. This flag march starting from Verka Milk Plant passed through Bhai Bala Chowk Ghumar Mandi Domoria Bridge  Raiway Station  Jagraon bridge Dholewl Chowk Bus Stand New courts Pakhowal Road and culminated at Phullanwal Ludhiana.

Smog Blankets Upper Indus-Ganga Plain

2nd Nov 2017
Heavy traffic also among contributing factors to the pollution

Smog covers the Upper Ganga Plain in India and Pakistan and settles in the valleys of the western Himalaya Mountains in this Suomi NPP VIIRS image from November 1, 2017. Cities of this region like Delhi are experiencing spikes in pollution levels and very poor air quality. Local news sources report heavy traffic, waste burning and crop fires to be contributing factors to the pollution. (Detail and Image Source:NOAA)
