"BROWN EARTH" mass-specific mineral scattering coefficient, bmin*(wavelength) in m^2/gm, for use by IOP routines. These values times the concentration of mineral particles in gm/m^3 give the scattering coefficient of the mineral particles in 1/m. These values are computed from Fig 4-3B and Table 3-II of Y-H Ahn, "Proprietes optiques des particules biologiques et minerales...," Univ. P. & M. Curie, Paris, France, 1990. The Ahn bb* values (Fig. 4-3B) are divided by bb*/b* = 0.0099 (Table 3-II) to get b*. bb* data were 400-700 nm. WARNING: Extrapolated by eye and splines to 300 and 1000 nm for use in H5.0 Spectrum may be unrealistic in the 300-400 and 700-1000 nm regions wavelen bmin* (nm) (m^2/gm) 300.0 0.60000 305.0 0.60141 310.0 0.60331 315.0 0.60564 320.0 0.60833 325.0 0.61136 330.0 0.61466 335.0 0.61821 340.0 0.62197 345.0 0.62591 350.0 0.63000 355.0 0.63423 360.0 0.63869 365.0 0.64348 370.0 0.64872 375.0 0.65453 380.0 0.66104 385.0 0.66838 390.0 0.67671 395.0 0.68619 400.0 0.69700 405.0 0.70918 410.0 0.72213 415.0 0.73509 420.0 0.74730 425.0 0.75800 430.0 0.76661 435.0 0.77344 440.0 0.77896 445.0 0.78366 450.0 0.78800 455.0 0.79233 460.0 0.79662 465.0 0.80075 470.0 0.80458 475.0 0.80800 480.0 0.81089 485.0 0.81328 490.0 0.81523 495.0 0.81679 500.0 0.81800 505.0 0.81893 510.0 0.81972 515.0 0.82054 520.0 0.82158 525.0 0.82300 530.0 0.82491 535.0 0.82712 540.0 0.82938 545.0 0.83142 550.0 0.83300 555.0 0.83387 560.0 0.83392 565.0 0.83304 570.0 0.83111 575.0 0.82800 580.0 0.82364 585.0 0.81821 590.0 0.81198 595.0 0.80516 600.0 0.79800 605.0 0.79066 610.0 0.78310 615.0 0.77521 620.0 0.76688 625.0 0.75800 630.0 0.74850 635.0 0.73848 640.0 0.72813 645.0 0.71758 650.0 0.70700 655.0 0.69652 660.0 0.68622 665.0 0.67615 670.0 0.66639 675.0 0.65700 680.0 0.64804 685.0 0.63949 690.0 0.63132 695.0 0.62350 700.0 0.61600 705.0 0.60881 710.0 0.60189 715.0 0.59522 720.0 0.58879 725.0 0.58256 730.0 0.57653 735.0 0.57068 740.0 0.56500 745.0 0.55949 750.0 0.55414 755.0 0.54894 760.0 0.54391 765.0 0.53903 770.0 0.53431 775.0 0.52976 780.0 0.52540 785.0 0.52122 790.0 0.51725 795.0 0.51350 800.0 0.51000 805.0 0.50676 810.0 0.50375 815.0 0.50096 820.0 0.49835 825.0 0.49590 830.0 0.49361 835.0 0.49144 840.0 0.48939 845.0 0.48743 850.0 0.48557 855.0 0.48378 860.0 0.48207 865.0 0.48041 870.0 0.47881 875.0 0.47726 880.0 0.47574 885.0 0.47427 890.0 0.47282 895.0 0.47140 900.0 0.47000 905.0 0.46862 910.0 0.46726 915.0 0.46593 920.0 0.46461 925.0 0.46333 930.0 0.46207 935.0 0.46084 940.0 0.45964 945.0 0.45848 950.0 0.45736 955.0 0.45629 960.0 0.45528 965.0 0.45432 970.0 0.45342 975.0 0.45261 980.0 0.45187 985.0 0.45123 990.0 0.45069 995.0 0.45028 1000.0 0.45000 -1.0 -1.0000
