When the White House’s National Science and Technology Council issued its latest report on Earth observation in April, one of the goals it set out was to improve user engagement. According to the National Strategy for Civil Earth Observations, ‰ÛÏMechanisms for engaging user communities will be developed to cultivate wider application and use of Earth observations.‰Û

The project is coordinated by TERC, a not-for-profit educational research organization in Cambridge, Massachusetts, specializing in math and science learning. SfA has designed practices, materials, and resources to make data and science more accessible and relevant to communities concerned about their local environment. Two stories, detailed here, illustrate the approach.

Table showing the schematic of a single SPoRT-LIS cycle. Each cycle is run every six hours from five days (d) before the current time (t) to nine hours (h) past the current time to provide the most up-to-date soil moisture information for situational awareness and model initialization.

Figure showing Difference plots (LIS minus control) of a 13-hour forecast valid at 1600 UTC, June 9, 2008, for the following fields: a) sensible heat flux (W m-2), b), 2-m dew point temperature (in degree Celsius), c) PBL height (m), and d) CAPE (J kg-1). Adapted from [5].A suite of real-time soil characteristic products for the contiguous United States will be enhanced by data from the upcoming Soil Moisture Active Passive (SMAP) and Global Precipitation Measurement (GPM) satellite missions. These products are used by operational weather forecasters to aid in analyzing and forecasting drought, extreme heat, and convective initiation.
