The term “won in a landslide” is particularly troubling to me because when a landslide happens, the kind that I study at least, there are seldom “winners”. My research looks at how rainfall interacts with the environment to cause natural disasters like flooding and landslides. Knowing where, when and how much rain or snow is falling is key to understanding where we may have extreme events that can impact people. If you consider where we get a lot of rainfall, like some of our tropical regions… ...and combine that with areas that have the right factors to cause a landslide, such as steep...

So, now that we have a satellite in space called SMAP, why is the data from the spacecraft so important? SMAP will help: Monitor Drought Predict Floods Assist Crop Productivity Improve Weather Forecasting Linking Water, Energy, and Carbon Cycles Read more HERE

To find our where the SMAP spacecraft is, at any time in relation to my school, you can check on the SMAP Orbit Calculator Tool! As you might have noticed in the SMAP Block Pattern Soil Moisture Protocol document, we recommend that measurements be taken and collected around 9:00am local time.  This is due to the SMAP spacecraft's 6am and 6pm local time equator crossings.  In order to have optimal SMAP comparison/validation data, it is vital to take your measurements as close to the 9am local time as possible. Any questions, please contact me at Brian.A.Campbell@nasa.gov Cheers...

Hi, my name is Anna Wilson. I moved to Asheville, NC in the summer of 2004, just before several floods caused by tropical storms left me without power for more than a week. This spurred my previously casual interest in the weather to become an obsession that eventually prompted me to go back to school. Here I am with a PARSIVEL disdrometer (an instrument that measures the size and velocity of particles that pass through its sampling area), after I completed my bachelor’s degree in Atmospheric Science and started working towards my PhD in Environmental Engineering: (photo credit: Daniel...

Hi Everyone, This past week and a half has been rather quiet as we performed two orbital maneuvers. The first maneuver placed the spacecraft at an altitude closer to its final orbit. The second one slightly adjusted the inclination of the orbit to ensure that SMAP goes over the equator at approximately 6:00 am and 6:00 pm every day, which are the ideal times to obtain our science measurements. For those of you wondering how SMAP maneuvers around, the spacecraft contains a single pressurized propellant tank carrying 81 kilograms (179 pounds) of hydrazine. The spacecraft adjusts its orbit...
