Data recipe for downloading a Giovanni map as NetCDF and converting its data to quantifiable map data in the form of latitude-longitude-data value ASCII text.Giovanni How-To’s on NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC) YouTube channel.Histogram plots are used to display the distribution of values of a data variable in a selected region and time interval.Area-averaged time series are used to display the value of a data variable that has been averaged from all the data values acquired for a selected region for each time step.Map animations are a means to observe spatial patterns and detect unusual events over time.Time-averaged maps are a simple way to observe the variability of data values over a region of interest.Giovanni is an online environment for the display and analysis of geophysical parameters. Panoply Orientation on NASA's Earthdata YouTube channel.Panoply offers additional functionality, such as slicing and plotting arrays, combining arrays, and exporting plots and animations. HDF and NetCDF files can be viewed in Panoply, a cross-platform application that plots geo-referenced and other arrays. Please visit the Earthdata Forum, where you can interact with other users and NASA subject matter experts on a variety of Earth science research and applications topics. Within the U.S., the United States Geological Survey's (USGS) National Landslide Hazards Program provides important information on identifying and monitoring landslides. NASA's Earth observation data provide important data to estimate landslide hazards. Earthquakes and changes to the landscape from wildfires, road building, and deforestation can also contribute to the instability of the land surface and cause landslides. Intense or prolonged rainfall is the most frequent extrinsic trigger of landslides, as it reduces friction between materials and increases the water pressure within the soil pores, increasing the likelihood of failure. There are numerous contributing forces to a landslide, many of which can be monitored or observed through remote sensing data. The mass movement of land (sediments and soils, bedrock and boulders, even whole mountainsides) down a slope is induced by the force of gravity. Landslides are some of the most common disasters in the world, killing thousands of people each year.
