Special Notice One Pyranometer and Three Kipp & Zonen model CGR4 Pyrgeometer, long wavelength solar radiation sensors

*** National Oceanic and Atmospheric Administration Sciences Laboratory (NOAA), Oceanic Atmospheric Research (OAR), Pacific Marine Environmental Laboratory (PMEL) intends negotiation, on a sole source basis, under authority of FAR 13.106-1(b)(1), with Environmental Analytical Systems, to purchase One Pyranometer and Three Kipp & Zonen model CGR4 Pyrgeometer, long wavelength solar radiation sensors. The original equipment manufacturer is OTT Hydromet Corp. To be delivered to Seattle, WA.

***The sole source determination is based on NOAA’s requirement that OTT Hydromet Corp is the only authorized vendor that PMEL is able to purchase long wavelength solar radiation sensors.  These highly accurate radiometers will be developed for use on Autonomous Sailing Vehicles (ASV's) from Saildrone Inc. PMEL requires Kipp & Zonen model sensors to be functionally identical to units that were purchased previously for a similar use on ASV Saildrones. These sensors will be deployed on Saildrone missions in support of the Atlantic Tradewind Ocean-Atmosphere Mesoscale Interaction Campaign (ATOMIC). Without continuity of this equipment, NOAA  mission of providing data may be compromised during deployment, delays in analysis, and/or the success of the overall project. Delivery is required by October 31, 2021.
