Crucial Hurricane Forecasting Tool to be Discontinued

Meteorologists are about to lose access to a pivotal tool that has been instrumental in forecasting hurricanes with precision.

This week, the National Oceanic and Atmospheric Administration (NOAA) announced a change in service that will halt the import, processing, and distribution of data derived from the Special Sensor Microwave Imager Sounder (SSMIS).

NOAA confirmed that this alteration in service will be definitive.

The SSMIS equipment is linked to three weather satellites orbiting the earth at low altitude. These satellites are a joint venture between NOAA and the Department of Defense, providing essential meteorological data that currently has no alternative sources.

This technology permits meteorologists to delve into the dynamics of active tropical systems, enabling a clearer understanding of their complexities. SSMIS utilizes microwave technology to penetrate cloud coverage, rendering a more accurate assessment of a storm's inner structure, including the pinpointing of its center.

Challenges of Other Satellite Technologies

Unlike SSMIS, other satellite systems dependent on visible and infrared imagery offer only superficial observations, mainly appraising cloud tops and are limited to daylight hours, leaving gaps in data collection post-sunset amid remote ocean expanses.

SSMIS data aids forecasters not only in tracking a tropical cyclone's current status but also in determining its central position for computational weather predictions.

Forecasting models are heavily influenced by starting conditions, necessitating reliable and ample data inputs. Experts caution that any disruption in the data stream could undermine forecast reliability.

Although other sources of microwave data exist, SSMIS constitutes a significant portion of these resources. Its absence could drastically curtail data availability, potentially leading to overlooked storm developments, particularly those escalating overnight, unnoticed by infrared systems alone.

Defense Meteorological Satellite Program

The SSMIS equipment forms part of the Defense Meteorological Satellite Program (DMSP), overseen by NOAA for the Space Force, which retains satellite management authority.

DMSP is responsible for creating and sustaining satellites that monitor atmospheric conditions, ocean states, and solar-terrestrial interactions.

A Space Force representative informed ABC News that the SSMIS data management is under the purview of the U.S. Navy, with further inquiries directed to them, although a response was not yet provided.

In their statement, Space Force confirmed that despite the switch within the Navy's operations, sharing of DMSP data remains unchanged, and is continuously accessible to non-DoD entities.

Concerns Among Scientists

Scientific experts nationwide voiced alarm over the decision, stressing potential negative impacts on the ability to accurately track and forecast dangerous cyclones.

Matthew Cappucci, an atmospheric scientist, highlighted on social media the detrimental effect this could have on hurricane forecasts crucial to safety in hurricane-prone areas of the United States.

Michael Lowry, a well-known hurricane specialist, wrote that the termination of SSMIS data will significantly degrade forecast capabilities, affecting millions residing along vulnerable coastlines.

Hurricane researcher Brian McNoldy also expressed urgency for those in hurricane-prone regions, seeing this as severe news.
