Description: | Comparisons of the RH probes with Oklahoma Mesonet probes in the laboratory and comparisons of the RH probes with the EBBR over a four day period after the Water Vapor IOP indicate the TOWER RH probes were incorrectly calibrated. Corrections required are summarized below. 60 meter level: RH data greater than 85% are incorrect for 23 May 1996 through 10 September 2000 GMT. RH data for 10 September 2330 GMT through 13 September 2130 GMT can be corrected with the following equation: -1.6 + 0.955*RH for original RH of 83% or less. Original RH values of greater than 83% cannot be adequately corrected. RH data for 14 September 0000 GMT through 30 September 2000 GMT can be corrected with the equation: -1.6 + 0.87*RH for original RH of 83% or less. Original RH values of greater than 83% cannot be adequately corrected. RH data for 30 September 2030 GMT through 21 October 1830 GMT can be corrected with the equation: 0.3 + 1.107*RH for original RH of 85% or less. Original RH values of greater than 85% cannot be adequately corrected. 25 meter level: RH data greater than 90% are incorrect for 23 May 1996 through 10 September 2000 GMT. RH data for 10 September 0000 GMT through 21 October 1830 GMT can be corrected with the equation: 4.098 + 0.953*RH for original RH of 90% or less. Original RH values of greater than 90% cannot be adequately corrected. Vapor pressure is also incorrect because RH was incorrect. Recalculate vapor pressure from the recalibrated RH. |
