Footnote A: Mount the CSI Krypton hygrometer vertical with its measurement path at roughly the boom height and 30 cm behind the intersection of the sonic acoustic paths (behind the internal vertical brace of the sonic head). On the horizontal array, mount the Krypton hygrometers on the west side of the sonics. On the 30 m tower, mount the Krypton hygrometers on the south side of the sonics, except at 5.5 m and 8 m where they should be on the north side of the sonics.
Footnote B: Mount the Licor-7500 on the west side of the sonic, tilted forward at a 45 degree angle from the vertical and with the mirror enclosure (at the top end of the Licor measurement path) centered vertically with the sonic head and just behind the internal vertical brace of the sonic head.
Footnote C: Sonics operating at 60Hz, CSAT rate parameter: "Ae".
