"CHLOROPHYLL-SPECIFIC ABSORPTION" coefficient, achl*(wavelength) in m^2/mg, for use by the IOP (ab) and chlorophyll-fluorescence routines. This file contains the ac*' data of Prieur and Sathyendranath, 1981, Limnol & Oceanogr, 26(4), 671-689, Table 2 Columm 3, scaled so that ac*(440nm) equals 0.05. This file is consistent with the Prieur-Sathyendranath-Morel model for absorption by Chl (Light & Water Eq. 3.27) as used in routine abcase1. Values below 400 and above 700 nm were extrapolated by eye. Note that the abcase1 model normalizes these values to 1 at 440nm, whereas fluorescence routine shatchl (in file shat.f) requires absolute values, as given here. wavelength a* (nm) (m^2/mg) 350 0.028 355 0.02825 360 0.0285 365 0.029 370 0.0295 375 0.03 380 0.0305 385 0.0315 390 0.033 395 0.0345 400 0.03635 405 0.03905 410 0.0414 415 0.04415 420 0.04565 425 0.04695 430 0.04865 435 0.05005 440 0.05 445 0.04855 450 0.0472 455 0.0464 460 0.04585 465 0.0451 470 0.0435 475 0.04195 480 0.0399 485 0.03865 490 0.0375 495 0.03585 500 0.0334 505 0.03225 510 0.0309 515 0.0291 520 0.0264 525 0.0252 530 0.0237 535 0.0222 540 0.0208 545 0.0192 550 0.01785 555 0.01605 560 0.0147 565 0.01365 570 0.0138 575 0.0134 580 0.01455 585 0.0137 590 0.0141 595 0.01245 600 0.0118 605 0.0120 610 0.0126 615 0.0134 620 0.0138 625 0.01495 630 0.01585 635 0.01665 640 0.0167 645 0.0163 650 0.0178 655 0.01945 660 0.02205 665 0.0267 670 0.02975 675 0.0272 680 0.0251 685 0.021 690 0.01645 695 0.0131 700 0.01075 705 0.008 710 0.0055 715 0.00375 720 0.002 725 0.0015 730 0.001 735 0.00075 740 0.0005 745 0 750 0 755 0 760 0 765 0 770 0 775 0 780 0 785 0 790 0 795 0 800 0 -1.0 -1.0
