冰核粒子(INP)在低于0摄氏度的温度下活动，由一系列生物产生并释放到环境中。当它们升空时，可能会影响云的性质和降水。到目前为止，我们对生物INP来源的了解是基于实验室研究的植被、土壤或水的抓取样本。通过对16个月的河水中INP浓度和河水排泄率的测量，我们得到了覆盖瑞士大部分地区的流域INP产量的下限(4 × 10 5 InP−8 m−2 d−1)。巧合的是，我们发现INP−8在被一场强降雨动员、冲入河流并从分水岭输出之前，可能至少在几个月内保持其在自然环境中催化结冰的潜力。
Ice nucleating particles (INP) active at a few degrees below 0°C are produced by a range of organisms and released into the environment. They may affect cloud properties and precipitation when becoming airborne. So far, our knowledge about sources of biological INP is based on grab samples of vegetation, soil or water studied in the laboratory. By combining measurements of INP concentrations in river water with river water discharge rates over the course of 16 months, we obtained a lower limit for the production rate of INP in a watershed covering most of Switzerland (4 × 105 INP−8 m−2 d−1). Coincidentally, we found that INP−8 are likely to retain their potential for catalysing ice formation in the natural environment for at least several months before they are mobilized by an intensive rainfall, washed into the river and exported from the watershed.
