| description | <p>The third phase of the Fifth International Ice Nucleation Workshop (FIN-03) was conducted at the Storm Peak Laboratory in Steamboat Springs, Colorado, in September 2015 to facilitate the intercomparison of instruments measuring ice-nucleating particles (INPs) in the field. Instruments included two online and four offline measurement systems for INPs, which are a subset of those utilized in the laboratory study that comprised the second phase of FIN (FIN-02). The composition of the total aerosols was characterized using the Particle Analysis by Laser Mass Spectrometry (PALMS) and Wideband Integrated Bioaerosol Sensor (WIBS) instruments, and aerosol size distributions were measured by a laser aerosol spectrometer (LAS). The dominant total particle compositions present during FIN-03 were composed of sulfates, organic compounds, and nitrates, as well as particles derived from biomass burning. Mineral-dust-containing particles were ubiquitous throughout and represented 67 % of supermicron particles. Total WIBS fluorescing particle concentrations for particles with diameters of <span class="inline-formula">></span> 0.5 <span class="inline-formula">µm</span> were 0.04 <span class="inline-formula">±</span> 0.02 cm<span class="inline-formula"><sup>−3</sup></span> (0.1 cm<span class="inline-formula"><sup>−3</sup></span> highest; 0.02 cm<span class="inline-formula"><sup>−3</sup></span> lowest), typical of the warm season in this region and representing <span class="inline-formula">≈</span> 9 % of all particles in this size range as a campaign average.</p>
<p>The primary focus of FIN-03 was the measurement of INP concentrations via immersion freezing at temperatures <span class="inline-formula">></span> <span class="inline-formula">−</span>33 °C. Additionally, some measurements were made in the deposition nucleation regime at these same temperatures, representing one of the first efforts to include both mechanisms within a field campaign. INP concentrations via immersion freezing agreed within factors ranging from nearly 1 to 5 times on average between matched (time and temperature) measurements, and disagreements only rarely exceeded 1 order of magnitude for sampling times coordinated to within 3 h. Comparisons were restricted to temperatures lower than <span class="inline-formula">−</span>15 °C due to the limits of detection related to sample volumes and very low INP concentrations. Outliers of up to 2 orders of magnitude occurred between <span class="inline-formula">−</span>25 and <span class="inline-formula">−</span>18 °C; a better agreement was seen at higher and lower temperatures. Although the 5–10 factor agreement of INP measurements found in FIN-03 aligned with the results of the FIN-02 laboratory comparison phase, giving confidence in progress of this measurement field, this level of agreement still equates to temperature uncertainties of 3.5 to 5 °C that may not be sufficient for numerical cloud modeling applications that utilize INP information.</p>
<p>INP activity in the immersion-freezing mode was generally found to be an order of magnitude or more, making it more efficient than in the deposition regime at 95 %–99 % water relative humidity, although this limited data set should be augmented in future efforts.</p>
<p>To contextualize the study results, an assessment was made of the composition of INPs during the late-summer to early-fall period of this study inferred through comparison to existing ice nucleation parameterizations and through measurement of the influence of thermal and organic carbon digestion treatments on immersion-freezing ice nucleation activity. Consistent with other studies in continental regions, biological INPs dominated at temperatures of <span class="inline-formula">></span> <span class="inline-formula">−</span>20 °C and sometimes colder, while arable dust-like or other organic-influenced INPs were inferred to dominate below <span class="inline-formula">−</span>20 °C.</p> |
