Continuous measurements of blowing snow are scarce, both in time and space. Satellites now provide the opportunity to derive blowing snow occurrences, transport and sublimation rates over Antarctica. These products are extremely valuable and offer a continental-wide assessment of blowing snow, which is an important but unknown component of the surface mass balance of the Antarctic ice sheet. However, little ground truth is available to validate these retrievals. The recent application of ceilometers for detection of blowing snow frequencies provides an opportunity to validate the satellite retrievals of blowing snow. A routine to detect blowing snow occurrence from ground-based remote sensing ceilometers has been developed at two coastal locations in East Antarctica for the 2011–2016 time period. Thanks to their ground-based location, ceilometers are able to detect blowing snow events in the presence of clouds and precipitation, which can be missed by the satellite, since optically thick clouds impede the penetration of the signal. In coastal areas, more than 90% of blowing snow occurs under cloudy conditions and represent 30 to 56% of all cloudy conditions at Princess Elisabeth and Neumayer III (Neumayer hereafter) stations, respectively. For cloud-free conditions, 8% of the measurements at Princess Elisabeth (and none at Neumayer) are identified as blowing snow by the satellite but not by the ceilometer, likely due to differences in sensors, limitation of the surface identification by the satellite, or the spatial inhomogeneity of the blowing snow event. While the satellite blowing snow retrieval is a useful product, further investigation is needed to reduce the uncertainties on blowing snow frequencies associated with clouds.

在时间和空间上都很难连续测量吹雪。现在，卫星提供了推算南极上空吹雪的发生，运输和升华率的机会。这些产品极有价值，可以对整个大陆吹雪进行评估，而吹雪是南极冰盖表面质量平衡的重要但未知的组成部分。但是，很少有事实依据可用于验证这些检索。云高仪在检测吹雪频率方面的最新应用为验证卫星对吹雪的获取提供了机会。2011-2016年期间，在南极东部的两个沿海地区开发了一种例程，该例程可通过基于地面的遥感云高仪检测吹雪的发生。由于他们位于地面，云高仪能够在有云和降水的情况下检测到吹雪事件，而卫星可能会漏掉这些云，因为光学上厚的云会阻碍信号的穿透。在沿海地区，超过90％的吹雪在多云的条件下发生，分别代表伊丽莎白公主和Neumayer III（以下称Neumayer）站所有多云条件的30％至56％。在无云的情况下，伊丽莎白公主（在Neumayer处没有测量）的8％测量被卫星而不是云高仪确定为吹雪，这可能是由于传感器的差异，卫星对表面识别的限制，或吹雪事件的空间不均匀性。卫星吹雪回收是有用的产品，
