Satellite Detects Food Chain Impact of El Nino 

Dan\'s Wild Wild Science Journal [2015-11-06 23:47:02]  recommend  recommend this post  (36 visits) info
El Nino is not just a warming of the surface waters in the East Pacific, the depth of that warm water increases as the thermocline lowers. This keeps nutrient rich colder waters from upwelling to the surface, impacting the very bottom of the food chain. NASA has a cool page (with much more info) where you can toggle back and forth and see the drop in chlorophyll here. How you

Adding projection data to ENVI headers (GIMMS 3g example) 

Digital Geography [2015-10-15 13:48:50]  recommend  recommend this post  (34 visits) info

Once in a while you may need to take an unprojected file and add coordinate parameters to the header. Assuming you use ENVI, the hard way is to perform a reprojection via Image to Map registration in ENVI Classic. The easy way is to add the coordinate information to the header file. Here we assume you do not need to warp the file to an ellipsoid or datum. Here we use the example of GIMMS 3g data from the University of Maryland and NASA. Start by importing the data as a Binary file.   It is [...]

The Hubble Telescope View of Jupiter is Amazing

From NASA: New imagery from NASA’s Hubble Space Telescope is revealing details never before seen on Jupiter. High-resolution maps and spinning globes (rendered in the 4k Ultra HD format) are the first products to come from a program to study the solar system’s outer planets each year using Hubble. The observations are designed to capture a broad range of features, including winds, clouds, storms and atmospheric chemistry. These annual studies

Why Running Water on Mars is a HUGE Discovery

On Earth, where you find water, you find life, so today’s announcement from NASA of flowing water on Mars is far more important than you might imagine. The photos from the Mar’s rovers look almost like the high desert of the American West, but remember  that Mars has only 1/100th of our atmosphere, and the temperature is well below zero most of the time. However, and this is key- when we

NASA: June 2015 ties with 1998 as Hottest On Record 

Dan\'s Wild Wild Science Journal [2015-07-16 00:35:09]  recommend  recommend this post  (34 visits) info
As greenhouse gases rise, we get more record hot months, but they are even more likely during an El Nino. Just like 1998, we have a strong one developing now. So far, this year is the warmest ever (Last year is currently the record holder), and 2015 has already seen a the hottest ever March and May, with January and February coming in as second hottest ever.

New Horizons Team Responds to Spacecraft Anomaly The New Horizons spacecraft experienced an anomaly the afternoon of July 4 that led to a loss of communication with Earth. Communication has since been reestablished and the spacecraft is healthy.

NASA: Warmest Jan.-April on Record. 2015 May be New Hottest Year On Record

The previous 12 month period was also the hottest on record and this breaks that record which was set just last month. With the daily increasing signs that a significant El Nino is brewing, we seem to be on track for another warmest year on record as well. El Nino’s really heat the atmosphere, and they tend to be among the warmer years almost always. Add in the rising greenhouse

This is really a great video from NASA, but what I like the most about it is how they explain a subtle fact of statistics that almost everyone, especially gamblers, basketball, and baseball players get wrong. With an El Nino brewing, we may see a quiet Atlantic tropical cyclone season. Like 1992, when we only had one storm make landfall on the coast of North America. Hurricane Andrew, a Category

The Larsen Ice Shelf is a huge piece of ice that sits on the other side of the Antarctic Peninsula from Rothera Station. It is divided into sections, which are named, from north to south (left to right, in the map), the Larsen A, B, and C. Back in 2002, a large piece of the Larsen B broke off into the ocean. The piece that broke off was 1,250 square miles, about the size of Rhode Island! It broke apart and fell into the ocean over a course of about a month. (You can see the satellite images of [...]

2014 Poised To Take Title as Hottest Year On Record

It is almost certain now that 2014 will be among the hottest years on record globally. The NASA (and NOAA), numbers are showing that it will likely be the absolute hottest, but it does depend on December temperatures. It would have to be an unusually cool December globally for a record to not be reached, and that is very unlikely based on how how warm the oceans are right now. | Impressum
