CREST has placed a particular focus on the improvement of flood monitoring and forecasting at local, regional and global scales to help NOAA to advance its capabilities in predicting and monitoring extreme events. Techniques to assimilate satellite imagery to infer river discharge and impact of ice on river hydraulics were developed by CREST scientist in joint project with NOAA experts. In addition, CREST scientists have successfully inferred precipitation intensity and extent as well as thunderstorm development. These accomplishments have been strongly consolidated by the implementation of several observation facilities such as weather stations, the NOAACREST Microwave Observation Unit which now comprises three dual-polarized radiometers and a dense in situ network. CREST will build upon its recent accomplishments and continue to support NOAA in reaching its goals, particularly in achieving a Weather-Ready Nation.
The research work under this theme maps to Weather Ready Nation and Resilient Coastal Communities and Economies Goals of NOAA and fulfill many of its remote sensing technology mission responsibilities which is perfectly in line with NOAA NESDIS and National Weather Service line of work.

The CREST-Snow Analysis and Field Experiment (CREST-SAFE) is being carried out to collect the long term intra-seasonal microwave and surface observations to analyze the snow transitional period from dry, wet, and to melting snow conditions. CREST-SAFE is setup in the backyard of the National Weather Service office at Caribou, ME using high frequency (37 and 89 GHz), dual polarized microwave radiometers to develop, improve and validate the snow retrieval algorithms. In addition to microwave radiometers, the field experiment site equipped with Snow Pillows (to measure Snow Water Equivalent), ultrasonic snow depth sensor, Infrared Thermometer (for Snow skin temperature), Net Radiation Sensors, Humidity, Temperature, snow temperature profiler (measures temperature at every 5 cm of snow layer), snow grain size, density, and network camera for real time remote monitoring of the site.
