It is well recognized that long-term precipitation measurements are necessary for understanding and monitoring regional precipitation characteristics. This includes characteristics crucial for monitoring water resources and hazards, like floods and droughts. TRMM was the first NASA mission dedicated to observing precipitation. It operated from November 1997 to April 2015. The Global Precipitation Measurement (GPM) Mission launched in February 2014 as a follow-on to TRMM. Both TRMM and GPM satellites, together with additional national and international satellites, were used to produce multi-satellite products such as TMPA and IMERG. Until recently these two separate products covered different time periods. There was a lack of long-term, continuous, precipitation time series.
Recently, GPM-IMERG retrospectively analyzed TRMM-TMPA data to produce a consistent, combined precipitation time series from 2000-present. This extended IMERG data product is available at half-hourly resolution and 0.1x0.1 degree spatial resolution. The product will be useful for deriving long-term mean precipitation as reference. It will also help with monitoring extreme precipitation at regional scale.
Past ARSET trainings on water resources and flood management covered TMPA and IMERG data and their applications in detail. This advanced webinar will focus on analysis and interpretation of the new long-term IMERG data, focused on extreme dry and wet period monitoring and management. The webinar will include lectures and hands-on exercises to derive regional precipitation statistics. Read More...

NASA's Applied Remote Sensing Training (ARSET) has opened registration for two new webinars. The first is New Sensor Highlight: ECOSTRESS.
The ECOSTRESS sensor is designed to study terrestrial ecosystems and plant water stress from the International Space Station, and can also be used to better understand crop health, volcanoes, urban heat, wildland fires, and coastal systems.
The second is a 3-part series, SAR for Disasters and Hydrological Applications
, and it will walk participants through the use of Google Earth Engine for flood mapping of radar data and presents two new topics: the use of InSAR for characterizing landslides and the generation of a digital elevation model (DEM). This training is also available in Spanish.
Please see the training details and registration information below. Read More...

A limitation of optical satellite remote sensing is that it depends on cloudless, well-illuminated areas to produce quality data. This is especially problematic for collecting data during nighttime or when there is cloud cover. Radar is an ideal sensor to study the surface of the Earth because of its ability to “see” through clouds regardless of day or night conditions. In addition, the radar signal can penetrate through the vegetation canopy and provide information about conditions underneath, such as flooding. Techniques such as interferometry can track surface deformation on the order centimeters, such as ground movement caused by earthquakes.
This webinar series builds on ARSET's previous webinar: Introduction to Synthetic Aperture Radar.
The training will focus on different radar approaches and techniques including amplitude, time-series, polarimetry, and interferometry for mapping and monitoring disasters and land cover. Attendees will apply these techniques to map land cover and land use change, deforestation, flooding, crop monitoring, and surface deformation for earthquake monitoring. Read More...

Up-to-date and accessible information is essential to providing an effective, coordinated response to disasters, such as earthquakes, floods, and tropical storms. The Global Disaster Alert and Coordination System (GDACS) provides near real-time data, alerts, and impact assessments that can be accessed online. ARSET is offering a webinar on the GDACS system this February. The training is targeted at local, regional, state, federal, and international organizations in the public and private sectors involved in disaster management. In this two-hour webinar, participants will learn how they can use GDACS to monitor real-time disasters, assess the impacts of an event, and develop response strategies for both national and international events.

ARSET is offering its first webinar series focused exclusively on soil moisture and evapotranspiration. The training is targeted at local, regional, state, federal, and international organizations interested in using satellite imagery for decision and policy-making activities.
Previous ARSET trainings focused on water resources have mainly addressed remote sensing measurements of precipitation and their applications. But precipitation is only one component of the water cycle. NASA's Soil Moisture Active Passive (SMAP) Satellite Mission is now providing new soil moisture data, and modeling frameworks are providing new evapotranspiration data. This webinar series will help attendees learn about NASA soil moisture and evapotranspiration products and how to access and apply them for water resource management. Over the course of five weeks, attendees will learn how to monitor and manage water resources with techniques learned in training. The series will begin with an introduction to satellite missions and useful data sets. Next, trainers will demonstrate online portals for accessing data. The series will conclude with specific examples of how you can apply the data and modeled data products. Read More...
