Hurricane Sandy

By now, you've most probably heard about the recent devastating hurricane in Eastern part of the U.S. It's called "Sandy". Sandy is expected to affect as many as 60 million Americans this week. Satellites and scientists are busy monitoring this weather phenomena. Thanks to CloudSat Data Processing Center, you can visually witness the vertical profile of Sandy along the CloudSat overpass track. The higher the radar reflectivity, the larger the amount of precipitation and cloud water would be.

Large Data in MATLAB [Upcoming Webinar]

If you are working with large dataset in MATLAB, then you won't like to miss this upcoming webinar by MathWorks. Most often, the issue in processing large data with MATLAB is lack of sufficient memory. In this webinar, you'll learn how to speed up processing large data using parallel computing and Graphical Processing Unit (GPU). A seismic data processing example will be use to illustrate how to perform faster data analysis computations. The webinar is set to be on 11 Jun 2012 from 9:00 a.m to 2:00 p.m EDT.

Google Ngram Viewer: What we learned from 5 million books

"Ngram Viewer" is a tool (in Google Labs) that provides you interesting statistical knowledge of 5 million books (500 billion words) from across centuries. The following video shows how it works. There is a link to the "Ngram Viewer" page.

It might seem simple, but you could still enjoy the power of data analysis revealing some interesting facts (knowledge) about social and cultural phenomena in the history.

Ferret: A Great Data Visualization And Analysis Tool

Ferret is an Interactive tool to utilize when you are dealing with large gridded and non-gridded datasets. Not only can it run on most Unix and windows machines, but also it can access remote Internet data sources through OPeNDAP (What is OPeNDAP?). This is a perfect data visualization and analysis tool particularly for meteorologists and oceanographers who mostly deal with global scale gridded data.

What is OPeNDAP?

My first experience with OPeNDAP was to use it in MATLAB to remotely access OPeNDAP served precipitation data. The applications of OPeNDAP however are much wider. "OpeNDAP is a framework that simplifies all aspects of scientific data. OPeNDAP provides software which makes local data accessible to remote locations regardless of local storage format. OPeNDAP also provides tools for tranforming existing applications into OPeNDAP clients (i.e., enabling them to remotely access OPeNDAP served data)." Moreover, it's FREE.

NASA's "Eyes on the Earth" Most Recent Version Released.

A while ago, I posted about the amazing NASA's "Eyes on the Earth 3D" system for visualization of the observing satellites that are constantly rotating around the Earth and sending us valuable information. Today, I would like to inform you about the release of the most recent version of this system. More interesting features have been added to this system. One of the main enhancements is the "Image of the Day" feature in collaboration with NASA JPL and NASA GSFC.

Make your own cluster in just a few minutes

Star Cluster is a revolutionary product. I say that not because it has novel idea, or a very complex product. Star Cluster, in my view, is a tool that democratize cluster computing power. It gives everyone access to high computational power with the lowest possible cost.
