Field Projects

field command vehicle in VORTEX2

Field research gives NSSL scientists a way to test new technology, check their theories, and propose new ideas about severe weather. NSSL researchers often go into the field to observe severe weather. They use radars mounted on trucks, cars with weather instruments on them, special cameras and vehicles for launching weather balloons to observe and record the atmosphere in and around storms.

mPING

Forms of frozen precipitation

The Hydrometeor Classification Algorithm (HCA) is continuously being refined using observations collected through NSSL's Meteorological Phenomena Identification Near the Ground (mPING) project. mPING is a project to collect weather information from the public through their smart phone or mobile device. Researchers compare the reports of precipitation with what is detected by the dual-polarized radar data.

Hazardous Weather Testbed (HWT)

Researchers in HWT

NOAA's Hazardous Weather Testbed (HWT) is jointly managed by NSSL, the Storm Prediction Center (SPC), and the National Weather Service Oklahoma City/Norman Weather Forecast Office (OUN). The HWT accelerates the transition of promising new meteorological insights and technologies into advances in forecasting and warning for hazardous weather events throughout the United States.

FLASH

Flood rescue

The Flooded Locations And Simulated Hydrographs Project (FLASH) was launched in early 2012 to improve the accuracy and timing of flash flood warnings. FLASH uses forecast models, geographic information, and real-time high-resolution, accurate rainfall observations from the NMQ/Q2 project to produce flash flood forecasts at 1-km/5-min resolution. FLASH project development continues to be an active collaboration between members of NSSL's Stormscale Hydrometeorology and Hydromodeling Groups, and the HyDROS Lab at the University of Oklahoma.

MPAR Software Upgrade Project

PAR data after DSP upgrade

Specific goals for this project are to improve the quality of meteorological data produced by the NWRT PAR, to demonstrate adaptive scanning capabilities for weather observations, and to demonstrate dynamic scheduling of multi-function scanning strategies.

Multi-Radar Multi-Sensor (MRMS)

MRMS display

The MRMS system produces severe weather and precipitation products for improved decision-making capability within NOAA. The automated algorithms in MRMS quickly and intelligently integrate data streams from multiple radars, surface and upper air observations, lightning detection systems, satellite and forecast models.

NMQ/Q2

NMQ display

The National Mosaic and Multi-sensor Quantitative Precipitation Estimation (NMQ) system uses a combination of observing systems ranging from radars to satellites on a national scale to produce precipitation forecasts. NMQ's prototype QPE products are also known as “Q2”—next-generation products combining the most effective multi-sensor techniques to estimate precipitation.

CI-FLOW

CI-FLOW logo

The Coastal and Inland Flooding Observation and Warning (CI-FLOW) project is a demonstration projection that predicts the combined effects of coastal and inland floods for coastal North Carolina. CI-FLOW captures the complex interaction between rainfall, river flows, waves, and tides and storm surge, and how they will impact ocean and river water levels.

PARISE

Phased Array Radar

Each spring, NWS forecasters evaluate how rapidly updating phased array radar data impacts the warning decision-making process in the Phased Array Radar Innovative Sensing Experiment (PARISE).

WDSS-II: On Demand

OnDemand display of tornado rotation tracks

NSSL's On-Demand, a web-based tool helps confirm when and where severe weather occurred by mapping circulations or hail detected by radar on Google Earth satellite images. NWS forecasters can quickly review warnings and check their accuracy with this system.

NSSL Weather Research & Forecasting Model (WRF)

WRF display

NSSL is working on ensemble forecast models for very short-range (0 to 60 minute) forecasts of severe weather events. Ensembles are groups of computer forecast models that are able to ingest Doppler radar, lightning or satellite data of thunderstorms to provide improved predictions of thunderstorms and their associated severe weather.

Forecasting a Continuum of Environmental Threats (FACETs)

WRF display

FACETs is a proposed next-generation severe weather watch and warning framework that is modern, flexible, and designed to communicate clear and simple hazardous weather information to serve the public. FACETs supports NOAA's Weather-Ready Nation initiative to build community resilience in the face of increasing vulnerability to extreme weather and water events.

FLOCAST

Floodwaters across road

The Flood Observations – Citizens As Scientists using Technology project (FLOCAST) will first use crowdsourced data about flooding and its severity collected through the mPING (meteorological Phenomena Identification Near the Ground) app available on smart phones. The FLOCAST team then targets the local emergency management community, who tend to provide the most accurate and detailed reports of flooding, and ask them to respond to a 5-minute web-based questionnaire. Researchers will use the information to better understand how society perceives, behaves and responds during flash-flood events, and improve the design, utility, and communication of information about impending flash floods to reduce loss of life.

FFaIR

Car awash in flood waters

A team from NSSL partners with the NOAA Hydrometeorological Testbed at the Weather Prediction Center in the Flash Flood and Intense Rainfall Experiment (FFaIR). FFaIR explores using high-resolution atmospheric and hydrologic models to improve short-term forecasts of both precipitation amounts and flash flooding.

Multifunction Phased Array Radar (MPAR) project

The Multi-function Phased Array Radar (MPAR) project was established to demonstrate the potential to simultaneously perform aircraft tracking, wind profiling, and weather surveillance with a single phased array weather radar. NOAA's National Weather Radar Testbed (NWRT) is a phased array radar (PAR) actively being tested and evaluated in Norman, Oklahoma.

3DVAR

3DVAR output

NWS forecasters are evaluating a new weather-adaptive 3DVAR system from NSSL/CIMMS that automatically detects and analyzes supercell thunderstorms. The 3DVAR system uses data from the national WSR-88D radar network and computer models to automatically locate regions of thunderstorm activity. It is able to identify deep rotating updrafts that indicate a supercell thunderstorm at 1 km resolution every five minutes in these regions. Initial development and testing of the 3DVAR was done at the Center for Analysis and Prediction of Storms at the University of Oklahoma.
