CIRA products at the 2026 Hazardous Weather Testbed
CIRA is demonstrating several products at this year’s Hazardous Weather Testbed (HWT). The HWT is a week-long workshop for National Weather Service forecasters and product developers. During the week the forecasters evaluate the demonstrated products’ usefulness in forecasting aspects of deep convection: initiation, strength, organization, hazards, etc. The forecasters interact with the product developers concerning the use of the products while examining the real-time weather during the week. CIRA’s products this year can be divided into two categories, synthetic imagery and optical flow products. In anticipation of the upcoming GeoXO GXI instrument, synthetic imagery at 0.865, 0.91 and 5.15 micrometer are being created using output from forecasts from the High-Resolution Rapid Refresh model. The channels are used to track low-level moisture, which is useful for forecasting convective initiation and maintenance. The optical flow products come from CIRA’s Optical flow Code for Tracking, Atmospheric motion vector, and Nowcasting Experiments (OCTANE) suite and include cloud-drift motion (speed and direction) products, cloud-top cooling products, as well as a MesoAnywhere product. The first of three sessions of the HWT completed May 1 and included forecasters from Boise, ID; Fairbanks, AK; Nashville, TN; and Pueblo, CO. (POCs: J. Haynes, J. Dostalek, J.

Evaporation and Filling of Lakes in the Sahara Desert
Evaporation and Filling of Lakes in the Sahara Desert
The Toshka Lakes, endorheic bodies of water in southern Egypt filled by overflow from nearby Lake Nasser, reached their lowest levels in the 2010’s. Heavy rainfall and flooding upstream saw the revival of the lakes in the 2020’s.
This satellite imagery from JPSS observes the shrinking and growth of the lakes over the last fourteen years.
Data Products
The Regional and Mesoscale Meteorology Branch (RAMMB) of NOAA/NESDIS conducts research on the use of satellite data to improve analysis, forecasts and warnings for regional and mesoscale meteorological events. RAMMB is co-located with the Cooperative Institute for Research in the Atmosphere (CIRA) at Colorado State University in Fort Collins, CO.
