- Description
- ***NOAA's Acquisition & Grants Office, Western Acquisition Division-Boulder, Office of Oceanic and Atmospheric Research (OAR), Global Monitoring Laboratory (GML), intends to negotiation, on a sole source basis, under authority of FAR 13.106-1(b)(1), with American Ecotech, LLC, out of Warren, RI, for an E010004 Ecotech Aurora-3000 multiwave length nephelometer. ***The sole source determination is based on the National Oceanic and Atmospheric Administration (NOAA) requirement that The Ecotech Aurora 3000 is the only instrument that provides measurements at the visible wavelengths required. The Aurora 3000 Integrating Nephelometer from American Ecotech measures aerosol light scattering at three visible wavelengths (450, 525, and 635 nm) and over two ranges of angular integration (9-170� and 90-170�). It outputs data at 1-second resolution and allows for automated zero air and span gas measurements at user-defined intervals. It can run autonomously and unattended for long periods (weeks to months) and can be controlled remotely by our GML software package. This instrument was developed and brought to market as a replacement for the TSI Model 3563 Integrating Nephelometer, which were produced since the mid-1990�s and went out of production in 2016. The specifications, wavelengths, and angular ranges are very similar between the two instruments. The aerosol light scattering measurements currently made in the NOAA Federated Aerosol Network are overwhelmingly made with one of these two instruments. Our own laboratory studies, as well as those of international workshops, have shown that the measurements produced by these two instruments are quite comparable (see, for example, M�ller et al., Atmos. Meas. Tech., 4, 1291�1303, https://doi.org/10.5194/amt-4-1291-2011, 2011). For long-term monitoring of the atmosphere, consistency in instruments and measurements is essential for accurate determination of trends and variabilities of atmospheric constituents. The NOAA CLAP instruments (in all, 38 of them in use across the NFAN) were designed and fabricated in GML to operate at wavelengths close to those in the TSI and Ecotech nephelometers. Light scattering and absorption measurements made at similar wavelengths are necessary to sufficiently minimize the uncertainty in measured aerosol optical properties so they can be used in climate models. This model is the only one that will provide for that consistency. Delivery of the units no later than 08/30/2022. ***THIS NOTICE OF INTENT IS NOT A REQUEST FOR COMPETITIVE PROPOSALS AND NO SOLICITATION PACKAGE IS AVAILABLE. HOWEVER, FIRMS THAT BELIEVE THEY CAN FULLY MEET THE GOVERNMENT'S REQUIREMENTS MAY SUBMIT SUBSTANTIATING DOCUMENTATION IN WRITING TO THE IDENTIFIED POINT OF CONTACT WITHIN 15 DAYS AFTER PUBLICATION OF THIS SYNOPSIS. SUCH DOCUMENTATION WILL BE EVALUATED SOLELY FOR THE PURPOSE OF DETERMINING WHETHER OR NOT TO CONDUCT THIS PROCUREMENT ON A COMPETITIVE BASIS. A DETERMINATION BY THE GOVERNMENT NOT TO CONDUCT A COMPETITIVE PROCUREMENT, BASED UPON RESPONSES TO THIS NOTICE, IS SOLELY WITHIN THE DISCRETION OF THE GOVERNMENT. ORAL COMMUNICATIONS ARE NOT ACCEPTABLE IN RESPONSE TO THIS NOTICE.
