Maximum wind speed data from aircraft reconnaissance mission SFMR
and dropsonde observations during Hurricane Harvey.
In 2012, we conducted a survey of the 13 facilities participating in the SFMR at that time to examine processes of care, including staffing, diagnostic appointment availability, tracking, communication practices with women and referring providers, and demographics of the population served not otherwise available in the SFMR (e.g., limited English proficiency [LEP]).
Using the SFMR database for all women with any type of mammogram during the study period, we measured the distribution of race/ethnicity (African American, Asian, Latino, White) and educational attainment (<high school graduate, high school graduate/GED, some college, [greater than or equal to]college) for the population served by that facility.
If we compare the Heston model , one of representative stochastic volatility models, with the SFMR
model, we can get some strengths.
During the 2005 season, only a few aircraft had the instrument available, but now each of the 53rd Weather Reconnaissance Squadron airplanes have the SFMR
, nicknamed "the Smurf." This constant measurement of surface winds gives the NHC a considerably more complete picture of the storm and can also determine rainfall rates within a storm system.

This multifrequency channel combination principle also led to the development of the SFMR
instrument (Harrington 1980), which measures the brightness temperature of the ocean surface using six distinct close-by C-band frequencies, which permit the simultaneous retrieval of both rain rate and surface wind speed.
The primary instruments on the WP-3D include the airborne tail Doppler radar, an X-band radar that provides reflectivity and radial (relative to the radar location) wind components in the presence of scatterers, a C-band radar mounted on the lower fuselage that provides reflectivity, dropsondes, flight-level instruments that measure standard atmospheric parameters, and the SFMR
. Though no airborne expendable bathythermographs were deployed, ocean conditions were measured by several Argo profiling floats (e.g., Roemmich et al.
During the IFEX flights, the WP-3D aircraft also featured a C-band lower-fuselage radar that provided reflectivity, flight-level instruments, and the SFMR
2003), or the aircraft-mounted stepped-frequency microwave radiometer (SFMR
; Jones et al.
These are computed from the difference in flight level (measured by WC-130J aircraft systems) and surface winds (measured by SFMR
) near the time of maximum storm strength (Fig.
