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. ...

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, ...

There are many application for SMAP soil moisture satellite data.
Understanding drought risk is vital to the health of the planet and to the lives of potentially billions of people around the world. Soil moisture strongly affects plant growth and hence agricultural productivity, especially during conditions of water shortage and drought. Currently, there is no global in situ network for soil moisture monitoring. Global estimates of soil moisture and plant water stress must be derived from models. These model predictions (and hence drought monitoring) can be greatly enhanced through ...

We all know that the SMAP satellite measures soil moisture. But, how does knowing our planet's soil moisture help us in understanding agriculture's reaction to it?
SMAP monitors soil moisture and provides critical information for drought early warning. In fact, a deficit in the amount of moisture in the soil defines agricultural drought. SMAP's measurements will come into play because researchers forecast a threefold increase in drought frequency in many regions of the world by the end of the 21st Century. History shows that a sustained drought can result in crop failure, deaths of ...

Hello from Medford Memorial Middle School in Medford, New Jersey.
The quest to get an accurate soil sample continues at Medford Memorial Middle School, Medford NJ. Hello, we are the students of Memorial’s Citizen Science Education Program. We’re excited to be part of the SMAP campaign, but have not yet been able to enter any data. Here’s a brief overview of our journey.
First, we learned about SMAP as a satellite, and then we studied the protocol. We didn’t have any soil sample cans, so we settled on a sturdy coffee can, Ryan had brought in from home. Ashwin measured 5 cm from ...

Guest Blog by NASA SMAP Scientists Dr. Erika Podest and Dr. Narendra Das of the NASA Jet Propulsion Laboratory in Pasadena, California USA.
SMAP scientists are using soil moisture in a number of ways, ways that allow all of us to better understand water’s role on Earth:
Weather Prediction : Water in the soil has the potential to evaporate (depending on atmospheric temperature and pressure) and when it does it plays a large role in cloud formation. Soil moisture also has a modulating effect on air temperature and humidity therefore having the ability to measure soil moisture ...

Have you ever wondered how the SMAP satellite, with an altitude of 685 km (425 miles) above the Earth, can take measurements as precise as the amount of water in the Earth's soil?
The quick answer is that it requires precisely calibrated instruments, along with a technological marvel in satellite design.
SMAP was designed to use a combination of two precise instruments, one with high resolution, one with high accuracy.
THE INSTRUMENTS:
Active (High Resolution): SMAP’s radar was designed accurately measure the echoes of very short radio frequency (RF) pulses that bounce ...

The SMAP Mission is vital to understanding our planet. Water is an essential source for life. By understanding the amount of water in the soil, or soil moisture, we can apply this information to many things.
Monitoring Drought
