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)

How your smartphone could one day predict the weather


How your smartphone could one day predict the weather

The article suggests that with humidity and barometric pressure measurements alone, it would be possible to predict the weather using a network of cell phones.  I guess this approach would have to filter out data from a cell phone, for example, in an air conditioned building where the air is essentially dehumidified in the cooling process, or a cell phone in in an oil heated building during the winter in the northern U.S., where the air becomes extremely dry.  Anyhow, the idea is  interesting and might be applicable for many other types of sensors that could estimate, for example, solar energy, air quality, human stress levels, traffic patterns, etc..

 

PR pitches broadband plan in DC

This issue is near and dear to my heart.  I live in the Llanos Tuna area of Cabo Rojo where we do not get Choice or PRT (Claro) internet.  We use HughesNet, a satellite-based  internet service, but it does not meet our needs, and is too expensive.  We have tried various cell phone-based approaches (Open-Mobile, Claro, Centenial) but we do not get good reception.  Not only that, the cell-phone approaches are slow and do not provide unlimited data downloading, as do Choice and PRT.  HughesNet allows us only 425 Mbytes per day, which we exceed frequently.  Downloading movies is out of the question.  If we exceed the amount then we are basically shut down for 24 hours!!  We do get some restore tokens each month, but if we use them up we have to pay $7 for additional restore tokens.  Every night before I go to bed I pray that someone will bring decent internet to my neighborhood. I will now focus my prayers on the success of the Puerto Rico’s Broadband Strategic Plan. 🙂

GOES-PUERTO RICO WATER AND ENERGY BALANCE (GOES-PRWEB) IS NOW OPERATIONAL


GOES-PRWEB is finally operational.  I would like to thank my student, Victor Reventos, who made it possible through his Python programming skills.  Here is a link to the results:

New results will be published daily.  Historical results are available from January 1, 2010. A list of the available output is provided below.
