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. ...

Water Availability can be defined as "The hydrologic capacity of a water source (surface water body, groundwater, municipal water) to sustain additional water demands after considering other current water uses and water conditions. (GEMI, 2012) The Soil Moisture Active Passive Mission provides information on water availability and environmental stress for estimating plant productivity and potential yield. The availability of direct observations of soil moisture status and the timing and extent of potential frost damage from SMAP enables significant improvements in operational crop...

The freezing and thawing of our planet's soil can make a big impact on our climate. Check out the blog below to see just how important this is. SMAP’s focus also includes measurements of freeze/thaw, which tells us whether the land surface is frozen or thawed in areas north of 45-degree north latitude. This is very important to know, because when the vegetation is frozen there is minimal exchange of gasses (CO2 primarily) between the vegetation and the atmosphere. It’s as if the vegetation were in a state of hibernation. This changes however, when spring begins and temperature rises...

"The Atlanta Science Festival is an annual public celebration of local science and technology. From March 19-26, 2016, curious people of all ages will explore the science and technology in our region and see how science is connected to all parts of our lives in 100 engaging events, including hands-on activities, facility tours, presentations, and performances throughout the metro Atlanta region." --- http://atlantasciencefestival.org/ On Saturday, March 19, there was a GLOBE/SMAP Training Workshops at the Captain Planet Foundation. Participants learned how to take soil...

How do SMAP Scientists Use GLOBE Data (Part II)? Data Analysis and Blog by Dr. Erika Podest, SMAP Scientist In order to start using GLOBE soil moisture data we need at least 15 measurements collected on days when SMAP flew overhead. The Varazdin School is an example of such and the chart below is a comparison between their data and SMAP soil moisture at 36 km 2 spatial resolution. Figure 2: Comparison between SMAP and GLOBE soil moisture from Varazdin school in Croatia. There are several things to note in Fig. 2. First, GLOBE measurements collected early on did not...

How do SMAP Scientists Use GLOBE Data (Part I)? Data Analysis and Blog by Dr. Erika Podest, SMAP Scientist SMAP has been collecting soil moisture measurements since mid-April 2015, which are freely available, online through the National Snow and Ice Data Archive Center (NSIDC): https://nsidc.org/data/smap Of utmost importance is to have an assessment of the quality of the data, which is why there is a SMAP calibration/validation group. Its purpose is to determine the accuracy of the measurements and whether there are any biases. In order to calibrate and validate the SMAP...

Did you know that soil moisture plays a vital role in human health? Those nasty little critters called mosquitoes love warm, wet soil, and can carry extremely dangerous viruses and diseases. We also can use SMAP soil moisture data to assist famine early warning systems. Improved seasonal soil moisture forecasts using SMAP data will directly benefit famine early warning systems particularly in sub-Saharan Africa and South Asia, where hunger remains a major human health factor and the population harvests its food from rain-fed agriculture in highly monsoonal (seasonal) conditions. In...

The NASA SMAP satellite took off for space on January 31, 2015 to study our planet's soil moisture and freeze/thaw state. Once in space, the satellite had to go through a prescribed series of steps to ensure that the spacecraft was functioning and all its instruments and components on-board were working properly. This took several months. In mid-April 2015, NASA starting receiving its first soil moisture measurements from SMAP's combined high resolution radar and its high accuracy radiometer. The combination of this data produced a data resolution of approximately 8km. Unfortunately,...
