I just came across a fascinating article titled "A Tale of Fire and Water- A NASA Scientist's Quest to Understand Rain in Africa". You can see this article at this link:http://earthobservatory.nasa.gov/Features/IchokuRain/.  You learn the story of a NASA scientist who grew up in southern Nigeria as a poor refugee child whose family was forced to flee their home because of a civil war that was raging in 1968. Not only is his story inspiring, but the use of various satellite data to explain Dr. Ichoku's research is really fascinating! The article covers many decades of changing climate...

Most cloud observations, including those using the GLOBE Observer app and even many from satellites, focus on the surface of clouds. It’s also useful, however, to be able to look inside clouds, especially storm clouds, to be able to get a picture of what’s going on now, and what might happen next. As an example, let’s look at Hurricane Joaquin, which was over the Caribbean in late September 2015. First, some ground observations from GLOBE overlaid on satellite surface reflectance data (below). On September 29th, the closest data point to the storm (center of image) is from Ramey School in...

I just came across an article that discusses the impact of the 2015-2016 El Nino on landslides in California. You can read it at this link: http://landslides.usgs.gov/monitoring/2015elnino/ncal.php. How would you think that the El Nino impacted the incidence of landslides in that region? Historically it is the large winter storms that cause the devastating landslides in the Francisco area. What do you think causes landslides to occur anyway? If you look at this website, you will learn about the different types of landslides and see records about how the El Nino conditions from...

As you might know, NASA came out with a statement that July 2016 was the hottest month on record, ever! Since the 2015-2016 El Niño event began in October 2015, each month has set a new record for the hottest month on record. Even though we are currently in a period of neutrality, we are on the tails of an El Niño and quite possibly about to enter a La Niña. "Since October 2015, every month has set a new global record for hottest temperatures. It coincides with an unusually strong El Niño Pattern which caused severe heat and drought across Southeast Asia, as well as raising...

I just read a fascinating article from National Geographic that was published yesterday entitled "How La Nina Could Affect the Spread of Zika": http://news.nationalgeographic.com/2016/08/will-la-nina-affect-the-spread-of-zika-/. Before you read the article, stop and consider how the temperature and precipitation patterns in your local region changed as a result of the El Nino. In my area, the greater Wash., D.C. metropolitan area, we had warmer temperatures and more precipitation. Then consider how the change in weather patterns might impact mosquitos- which in my case would mean more...

Plants need light to grow. They also require nutrients. For tiny marine plants, called phytoplankton, those nutrients are often brought up from the ocean’s cold, deep waters to the surface by mixing. But this normal circulation gets disrupted during El Niño years, when huge masses of warm water—equivalent to about half of the volume of the Mediterranean Sea—slosh east across the Pacific Ocean towards South America. The change can have fatal consequences for phytoplankton in the eastern equatorial Pacific. Here is the full story with associated images and video!

Check out the latest and greatest images, from NASA, associated with the El Niño Southern Oscillation (ENSO) event. These images that you will see show sea surface height anomalies with the seasonal cycle (the effects of summer, fall, winter, and spring) removed. The differences between what we see and what is normal for different times and regions are called anomalies, or residuals. When oceanographers and climatologists view these "anomalies" they can identify unusual patterns and can tell us how heat is being stored in the ocean to influence future planetary climate events. Each image...

10. El Niño Student Campaign Refresher and Update -  Wednesday, September 21st, 2016 8:00 pm EDT (12:00 am September 22nd UTC) In this hour-long webinar, participants will get a refresher on this campaign, and will hear from several GLOBE teachers who have been involved with their classes from the start of the campaign. We will discuss the need for ongoing data collection and share the current state of the ENSO cycle.  We will have a NASA scientist discuss the current state of the ENSO cycle and what it might mean for weather conditions for the remainder of this campaign. Link...

A heat lamp and reflector socket with a spring clamp may be purchased on-line for as little as $26. The amount of time required to dry samples depends on many things including the wetness of the initial sample, the soil characteristics, the relative humidity, and the temperature to which the sample is heated. GLOBE protocols specify that samples are not to be heated above 105o C. In using a heat lamp, the temperature to which the sample is heated depends on the wattage of the bulb and the distance between the heat lamp and the sample bag. I have tried drying a sample using this...
