NASA: Advanced Webinar: Techniques for Wildfire Detection and Monitoring

This is event is available for participation on an ongoing basis
Undefined

NASA's Applied Remote Sensing Training Department is offering a new webinar on wildfire detection on July 19th, 2018 from 18:00-20:00 EDT (UTC-4). Following the event the webinar will be available as a recording. 

In light of increasing drought and wild fire frequencies, the first session describes key aspects of satellite based wildfire monitoring and introduces a new QGIS plugin: "QGIS Fire Mapping Tool (FMT)". The second session gives an overview of the Global Wildfire Information System (GWIS) and demonstrates how to use the GWIS viewer.

New recommeneded practice on drought monitoring published

UN-SPIDER published a new recommended practice in its Knowledge Portal outlining detailed step-by-step procedures to support drought monitoring. The practice was developed by researchers from the Federal University of Santa Maria in Brazil (UFSM).  The procedure has been used to elaborate drought-related maps for Brazil in recent years.

Detecting forest fires with satellites (MODIS and VIIRS)

Since several years ago, satellites have been used to detect fires. The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard NASA’s Terra and Aqua satellites has been used to scan the Earth’s surface for fires on a daily basis for almost 15 years. Since 2012, the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard the Suomi NPP satellite has contributed to this effort by producing higher resolution images of the Earth’s surface.

NASA’s Earth observation Aqua satellite spotted the wildfires burning throughout California, Oregon, Washington, Idaho and Montana states on August 23. One of the most important blazes was reported in the Okanogan Complex, in Washington State. It has burned 287,704 acres (116,000 hectares) and killed three firefighters. More than 1,774 fire personnel from 33 states are currently fighting it or working to support the firefighting effort.

NASA satellites show: Earth is a cloudy place

Decades of satellite images show: Earth is a cloudy place (Image: NASA)

Satellite-based Earth observation as well as images taken by astronauts show that Earth views from space are dominated by clouds. A recent study by NASA has looked at a decade of imagery and estimates that about 67 percent of Earth’s surface is typically covered by clouds.

Satellites show earlier snowmelt in Wyoming, USA

A new NASA study about snowmelt in Wyoming shows, that the snow in a basin in northwest Wyoming now disappears about 16 days earlier than it did in the period from the 1970s through the 1990s. Snowmelt, as a water source, has a significant impact on agriculture and ecosystems in Wyoming.

Satellites capture exceptional 2014 floods in Bangladesh

The flooding has been particularly strong along the Brahmaputra River

Bangladesh is one of the most flood-prone countries in the world. However, a combination of heavy monsoon rainfall and the arrival of meltwater from the Himalayas has led to exceptionally heavy floods in Bangladesh in the summer of 2014. NASA's Terra satellite has captured a scene in late August showing flooded areas along the Brahmaputra River and the Tanquar hoar wetlands.

Philippines: Satellites track Typhoon Rammasun

Typhoon Rammasun
In this map, based on TRMM data, heavier rainfall is shown in dark blue.

On 15 and 16 July 2014 Typhoon Rammasun swept across the southern Philippine islands of Luzon as a category 3 storm. The typhoon made landfall with 200 km dropping 200 millimeters of rain on Luzon, Samar, and Panay.  Official have attributed 20 deaths to Rammasun’s high winds blowing down trees and power lines but claim that the damage could have been worse. Applying lessons learned from Haiyan 8 months prior more than 400,000 people evacuated their homes in the storm’s path.
