Small Scale Farming: Simple, Successful, Sustainable


Small Scale Farming: Simple, Successful, Sustainable

Sugeno-san is a philosopher. His love affair with the land is poetry. “These trees are planted by our ancestors. These ‘tambos’ — the orderly descending terraces of rice paddy fields — are blessings from our communal mountains and forests. We smallholder farmers are the guardians of this Earth.

Replacement Weather Satellite for GOES East


Replacement Weather Satellite for GOES East

This is bad news for the Caribbean Region.  And this is very bad news for those of you that regularly download solar radiation data from pragwater.com or rely on results from GOES-PRWEB.  The National Oceanic and Atmospheric Administration (NOAA) confirmed Monday that GOES-13 has been placed in stand-by mode, following increased vibrations, or “noise,” observed in imagery over the past couple of days.  For more information visit http://www.accuweather.com/en/weather-news/key-us-weather-satellite-goes/78844

This post has implications on data from the following pragwater web pages:

This composite satellite image from Sunday shows a lack of data from GOES-13 over the east coast of the U.S. (CIMSS Satellite Blog)
