Description: | IN THE BEGINNING (June 1992), the retrieval coefficients used to derive the precipitable
water vapor (PWV) and liquid water path (LWP) from the MWR brightness temperatures were
based on the Liebe and Layton (1987) water vapor and oxygen absorption model and the Grant
(1957) liquid water absorption model.
Following the SHEBA experience, revised retrievals based on the more recent Rosenkranz
(1998) water vapor and oxygen absorption models and the Liebe (1991) liquid waer absorption
model were developed. The Rosenkranz water vapor absorption model resulted a 2 percent
increase in PWV relative to the earlier Liebe and Layton model. The Liebe liquid water
absorption model decreased the LWP by 10% relative to the Grant model. However, the
increased oxygen absorption caused a 0.02-0.03 mm (20-30 g/m2) reduction in LWP, which was
particularly significant for low LWP conditions (i.e. thin clouds encountered at SHEBA).
Recently, it has been shown (Liljegren, Boukabara, Cady-Pereira, and Clough, TGARS v. 43,
pp 1102-1108, 2005) that the half-width of the 22 GHz water vapor line from the HITRAN
compilation, which is 5 percent smaller than the Liebe and Dillon (1969) half-width used in
Rosenkranz (1998), provided a better fit to the microwave brightness temperature
measurements at 5 frequencies in the range 22-30 GHz, and yielded more accurate retrievals.
Accordingly, revised MWR retrieval coefficients have been developed using MONORTM, which
utilizes the HITRAN compilation for its spectroscopic parameters. These new retrievals
provide 3 percent less PWV and 2.6 percent greater LWP than the previous retrievals based on
Rosenkranz (1998).
Although the MWR data will be reprocessed to apply the new monortm-based retrievals, for
most purposes it will be sufficient to correct the data using the following factors:
PWV_MONORTM = 0.9695 * PWV_ROSENKRANZ
LWP_MONORTM = 1.026 * LWP_ROSENKRANZ

PYE/M1 (Pt. Reyes) 4/08/2005, 1900**
** At Pt. Reyes, the original retrieval coefficients implemented in March 2005 were based
on a version of the Rosenkranz model that had been modified to use the HITRAN half-width
at 22 GHz and to be consistent with the water vapor continuum in MONORTM. These
retrievals yield nearly identical results to the MONORTM retrievals. Therefore the Pt. Reyes
data prior to 4/08/2005 may not require reprocessing. |

Subject: | NSA/SKYRAD/C2 - Reprocess: Incorrect datalogger program affecting PIR1 and PIR2 downwelling longwave |
DataStreams: | nsaskyrad20sC2.a0, nsaskyrad60sC2.b1
|
Description: | The excitation delays using in measuring the PIR1 case thermistor commonly named "Case1"
and the PIR2 dome thermistor called "Dome2" were discovered to have been incorrectly set
to 0 in the Skyrad datalogger program when the new CR23X based Skyrad loggers were
installed. The result of no delay in these measurements results in an error in the measured
resistance of the thermistors, Case1 and Dome2 and thus the calculated PIR1 and PIR2
irradiances. The errors are inversely proportial to temperature.
Users can apply temperature dependent irradiance corrections shown in the table below.
Recall that the reported uncertainty of PIRs is typically +-.25% to +-.5% or 1 to 2 W/m2.
The error corrections become the same order of magnitude or larger than the instrument
uncertainties at or below 260K or 9F.
