Proenza had a rocky tenure as the chief of the NHC -- "a brief but turbulent tenure in which he publicly criticized his bosses and then lost the support of much of his staff." In May 2007, he publicly accused NOAA of wasting money, specifically citing NOAA's plans to spend $4 million to publicize a 200th anniversary celebration while the agency has cut $700,000 from hurricane research. In its defense "NOAA spokesman Anson Franklin said the agency is actually only spending about $1.5 million on the campaign over two years. He said it is justified to publicize the agency's mission to a public that is often unaware of its involvement in weather prediction and forecasting." Proenza had been particularly outspoken in his desire to see a replacement for the aging QuikSCAT satellite, which measures surface winds over remote ocean areas, citing a study that says "the center's ability to track storms could dip as much as 16 percent when the satellite dies." Three senior researchers, however, complained that Proenza overstated his case, unduly alarming the public and compromising the center's credibility. Jeff Masters, former NOAA meteorologist and operator of Weather Underground, said Proenza relied on an imperfect, unpublished study. Masters pointed to a different, more complete study, which stated that QuickSCAT's loss would have at most a "minor effect". The criticism snowballed, and in early July, he faced an open revolt as half of the center's employees signed a letter calling for Proenza's departure. The South Florida Sun-Sentinel described the letter: As early as June 2007, National Oceanic and Atmospheric Administration administrator Vice AdmiralConrad Lautenbacher initiated an investigation into Proenza's management of the National Hurricane Center, prompted by concerns from Mary Glackin, acting director of the National Weather Service. On June 26, Lautenbacher received permission from Secretary of Commerce Carlos M. Gutierrez to take action against Proenza should it be necessary. Lautenbacher requested that the National Institute of Standards and Technology form an independent "management assessment team" which would travel to the National Hurricane Center and evaluate the management situation. This team was personally headed by NIST deputy director James Turner, who delivered the team's final report. The above-mentioned letter was signed by the employees while the assessment team was visiting the hurricane center. This fact caused Proenza to speculate that the letter signing may have been engineered by vengeful NOAA management. On July 9, 2007, Proenza was placed on administrative leave. Deputy director Edward Rappaport took over as interim director. On July 13, the management assessment team formally delivered its final report to administrator Lautenbacher. The report concluded that Proenza's management style was ineffective, that his continued presence would interfere with the ability of the National Hurricane Center to perform its vital functions, and that Proenza should be removed as director of the center. Lautenbacher then requested that the NIST assessment team formulate specific recommendations within 2 weeks. At a joint congressional subcommittee hearing on July 19, Lautenbacher testified that he had not yet determined what final actions would be taken regarding Proenza and the National Hurricane Center. He stated, however, that his final decision would be based entirely on the recommendations of the assessment team.
Accomplishments
Proenza was a councilor for the National Weather Association in 1991. The NWS Employee's Organization recognized him as the NWS manager of the year for 1998. The NWS Employees' Organization also recognized Proenza nationally as the NWS Manager of 1998 for his collaborative leadership with their union. In 2001, the American Meteorological Society recognized him with its prestigious Francis W. Reichelderfer Award for outstanding environmental services to the nation.
