CIRIMS Deployments 1999-2002

CIRIMS onboard the R/V Thomas G. Thompson


One of the earliest deployments of the CIRIMS was on a student instructional cruise aboard the UW R/V Thomas G. Thompson from Seattle to Hawaii from 11/03/99 to 12/01/99. This location proved to be unacceptable because of the location of the wake and exposure during severe weather.

CIRIMS onboard the USCG Polar Star

CIRIMS was deployed with on the USCG icebreakers Polar Star (7/24/00 to 9/22/00) and Polar Sea (11/04/00 to 5/17/01) for side-by-side comparison to the M-AERI. The Polar Star cruise to the Arctic and the Polar Sea cruise to Antarctica provided the opportunity to demonstrate reliability under severe weather conditions.

**CIRIMS onboard the R/P FLIP during FAIRS**


The Fluxes, Air-sea Interaction, and Remote Sensing (FAIRS) Experiment took place on the R/P FLIP from 15 Sep to 15 Oct 2000 off the coast of Monterey, CA. The CIRIMS was used in conjunction with a wave-following thermistor chain to provide continuous measurements of the bulk-skin temperature difference.

**CIRIMS onboard the R/V Ronald H. Brown during 2001**

The most extensive and successful deployment of the CIRIMS was from 1/24/01 to 12/14/01 on the R/V Ronald H. Brown. The CIRIMS was deployed in the 10-m bow tower shown in the photographs. This location is ideal because it provides a view of the surface well ahead of the bow wake and is not subject to heavy spray during severe weather. We have chosen to mount the CIRIMS on the flying bridge for subsequent deployments because the tower was permanently removed. The flying bridge location was chosen after careful analysis of the location of the wake using aerial photographs of the Brown and in situ measurements using a laser-based alignment system.

**CIRIMS onboard the R/V F. G. Walton Smith during the RSMAS Intercomparison**

From May 28th to June 1st, 2001, the Rosenstiel School of Marine and Atmospheric Science hosted an intercomparion of self-calibrating surface-based radiometers onboard the R/V F. G. Walton Smith. The intercomparison provided an opportunity for the cross calibration of 7 different sea surface temperature radiometric instruments. The results of the intercomparison are reported in the following article (contact Andy Jessup for preprint): Barton, I. J., P. J. Minnett, K. A. Maillet, C. J. Donlon, S. J. Hook, and A. T. Jessup, The Miami2001 infrared radiometer calibration intercomparison: 2. Ship-board results, to appear, J. Atmos. Ocean. Tech., 2003.

On the right is SISTeR (Scanning Infrared Sea Surface Temperature Radiometer), deployed by Tim Nightingale of the Rutherford Appleton Laboratory.
