Advanced Webinar: Applications of GPM IMERG Reanalysis for Assessing Extreme Dry and Wet Periods

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.

Two New Training Opportunities from NASA's Applied Remote Sensing Training Program

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.

Launch of NCCWSC 2018 Fish and Game Webinar Series

In 2018, the National Climate Change and Wildlife Science Center (NCCWSC) is focusing their webinar series on science related to fish and game issues with presentations from NCCWSC and each regional Climate Science Center. Our first presentation, “Foraging Decisions and Populations Dynamics: Ungulates under a Warmer Climate”, will take place on Thursday, February 22.

Series of Webinars from USAID and Climatelinks

USAID is sharing world-class climate knowledge, data and tools to ensure countries can predict, prepare for and adapt to change. USAID also helps countries lay the foundations for sustainable growth powered by clean energy and healthy landscapes.

In keeping with this mission, USAID and Climatelinks are offering a series of free webinars this month covering various climate adaptation topics. For the full list, read more below.

Fundamentals of Remote Sensing

These webinars are available for viewing at any time. They provide basic information about the fundamentals of remote sensing, and are often a prerequisite for other ARSET trainings.

Learning Objectives:
Participants will become familiar with satellite orbits, types, resolutions, sensors and processing levels. In addition to a conceptual understanding of remote sensing, attendees will also be able to articulate its advantages and disadvantages. Participants will also have a basic understanding of NASA satellites, sensors, data, tools, portals and applications to environmental monitoring and management. Read More...
