ATMOSPHERIC ENVIRONMENT FOR PERSHING MISSILE-403

I. INTRODUCTION

This report presents the more important portions of availableatmospheric information pertinent to the missile flight at 1945 ESTon 14 February 1963, from Cape Canaveral, Florida. Surface and upperair observations were made as close to missile launch time as possi-ble at the launch site and downrange at Grand Bahama Island.

Rocket measured winds were determined from radar track of aLOKI II meteorological rocket flight provided by the PAFB AirWeather Service in support of PERSHING Missile-403.

This information is presented to document in detail the atmos-pheric conditions prevailing at time of missile launch and to providesupporting material for specific atmospheric investigations inconnection with missile design and/or missile flight-mechanicalperformance studies.

II. PRESENTATION AND DISCUSSION OF DATA

A. Source of Data

The general synoptic situation was taken from weather mapsmade by the U. S. Weather Bureau on missile firing date (Figs. 1, 2,and 3) and from data furnished by the Patrick Air Force Base Weatherstation.

Surface and upper air observations were made at the CapeCanaveral launch site and downrange stations under the supervisionof the U. S. Air Force. These observations were made as close tothe missile launch time as possible.

A LOKI II meteorological rocket furnished by the U. S. AirForce was fired in support of Pershing Missile-403.

B. Methods of Computation and Presentation

Wind speed and direction, temperature, pressure, and rela-tive humidity are measured by rawinsondes. Thermodynamic quantitiesare computed from the rawinsonde data by use of the hydrostaticequation and its modifications as given in the Smithsonian Meteoro-logical Tables (Ref. 1). Thermodynamic values are then determinedfor each 250 meters of altitude above sea level by interpolation.

1

Wind data are also interpolated at 250 meter intervals of altitudeusing the altitude references computed from the hydrostatic equation.Rawinsonde wind data are considered unreliable at high altitudes andlow elevation angles (less than 101). Wind shears are computed foreach 250 meter interval of altitude from the rawinsonde data.

Temperatures are fitted by logarithmic interpolation betweenthe ceiling of the rawinsonde temperature curve and the ARDC tempera-ture curve of 9.5C (282.66K) at the 1 mb pressure height. TabulatedARDC temperatures are used above the 1 mb pressure level and densityis computed as before.

The index of refraction is computed by use of the formulagiven in "Analysis of Refractive Index Errors", by Epstein (Ref. 2).

The rawinsonde measured atmospheric parameters are comparedto the Patrick Air Force Base Reference Atmosphere (Ref. 3), bysubtracting the reference atmosphere values from the rawinsonde valuesat corresponding altitudes.

C. General Synoptic Situation at Missile Firing Time

A very flat high pressure ridge extended from the vicinityof Brownsville, Texas across the Gulf of Mexico anu V.ii c!'n 1A.orida.A 1033 mb high was centered over northeastern North taiuti wit h ci

ridge extending south-southeastward. This immense high.covered theentire eastern two-thirds of the United States north of a cold frontwhich extended from a weak low (1002 mbs) over Massachusetts south-westward over eastern North Carolina, through central Georgia,southern Louisiana to southeast Texas where it became stationary andextended to the north-northwest along the eastern slopes of theRockies. This front was very weak through the Carolinas to southernLouisiana with no associated clouds. Cloudiness over Florida duringcountdown and launch consisted of a few scattered stratocumulusthrough central and south Florida with patchy middle and high cloudsover the Keys. Surface winds were west-southwesterly with speeds of5 m/sec or less. Visibilities were 10 miles or more. Impact areaconditions were clear to scattered cumulus with some patches of thincirrus,

Winds aloft were WNW to W up to 4 km; above 4 km winds werewest-southwesterly to approximately 21 km above which they becamevariable, Maximum speeds of 73 m/sec were observed at the 9.75 to10.25 km levels in the upwind release.

This information is given in the table on page 4.

2. Wind Data

Launch site and downrange wind data are shown inFigures 4 and 5o Surface winds were west at 3.1 m/sec at the Capeand were calm at GBI0 Winds aloft at both the Cape and GBI werewest-northwest by 2 km altitude and backed slowly to become west-southwest by 10 km altitude, Reliable wind data terminated at 11 kmaltitude for GBIo Wind direction at the Cape continued from west-southwest from 10 km to 20 km and was variable from there to termi-nation of the data at 30.75 km altitude. Maximum wind speed at theCape was 73 m/sec at 9,75 km and 10.25 km altitude. GBI had amaximum wind speed of 78 m/sec, also at 9.75 km altitude.

The wind components are shown in Figures 6 and 7. Atailwind from the right was observed from the surface to 21 km atCape Canaveral and was variable in both the range direction andcross-range components above 21 km altitude. At GBI tailwinds fromthe right were observed from just above the surface to terminationof reliable data at 11 km altitude. Maximum range direction windcomponent at the Cape was a tailwind of 57.2 m/sec at 11.5 kmaltitude.

The rawinsonde measured wind shears computed at evenaltitude increments of 250 meters each are shown in Figure 8.

Wind data computed from radar data for the meteorologicalrocket flight are shown in Figures 9 and 10. Two maximum speedsare shown in the data. One at 43.5 km altitude of 36.5 m/sec andanother at 53 km altitude of 45°5 m/sec. The data above 50 km arequestionable.

3. Thermodynamic Quantities

Rawinsonde measured ambient temperatures (Fig. 11) werebelow the PAFB standard atmosphere at both the Cape and GBI from thesurface to 11 km altitude (Fig. 12). From 11 km to near 14 kmtemperatures were above standard at both stations. It was belowstandard from there to termination of the data for GBI. The Capehad another above-standard layer near 20 km, but with that exceptionwas below the standard from near 14 km to termination of the data.Maximum temperature deviation from the PAFB standard was 4.7 percentbelow standard at 1.25 km altitude for the Cape and 4,0 percentbelow standard at 17.5 km for GBI.

5

Pressure at both the Cape and GBI was below thestandard at all altitudes from 1 km to termination of the data(Fig. 12). Maximum deviation was at the highest altitude reached;31.5 km at the Cape with 5.7 percent below standard, and 28.75 kmat GBI with 6.4 percent below standard.

Density was above the standard from the surface to6.5 km at Cape Canaveral (Fig. 12). From there to termination ofmeasured data density was below the standard. Maximum deviation of5.8 percent above standard was measured at the surface at CapeCanaveral. The maximum density deviation for GBI was 3.6 percentabove standard at 1.5 km altitude.

The virtual potential temperatures for the Cape andGrand Bahama Island are shown in Figure 13. Figure 14 shows tempera-ture lapse rates for the Cape.

Relative humidity (Fig. 15) was slightly lower thanthat in the reference atmosphere from the surface to 500 metersaltitude for both the Cape and GBI. An increase in moisture contentbegan at near 500 meters and by 1.25 km altitude relative humidityat the Cape was near the reference atmosphere while that at GBIwas above. Above 2 km the relative humidity remained below 20percent except for a moist layer near 9 km altitude at GBI where itwent above 65 percent.

The index of refraction for Cape Canaveral and GrandBahama Island is shown in Figure 16. The Reference Atmosphere forPAFB is shown in Figure 17. Absolute deviations of the index ofrefraction (Fig. 18) for the Cape and GBI follow similar patterns,but with the largest deviations being at the Cape; (n-l)106 = 44.5units below the reference atmosphere at 1.75 km altitude.

III. CONCLUSIONS

Surface winds at the Cape at launch time were westerly 3.1 m/sec.Winds increased in speed aloft to become 73 m/sec at 9.75 km altitude.

Scattered cirrus clouds were reported at the Cape and clearskies at Grand Bahama Island.
