Antarctic precipitation climatologies from CloudSat Cloud Penetrating Radar, 2007-2010

Two Antarctic snowfall climatologies produced from the version R04 of the CloudSat 2C-SNOW PROFILE product are available here. The climatologies cover the period 2007-2010 and the area between 55 and 82 °S. The snowfall rate in the file \"CloudSat_2C-SNOW PROFILE_Antarctica_20072010_SRSinf4.nc\" has been calculated using only the observations with a snow retrieval status lower than 4 (Wood et al., 2013, Palerme et al., 2018). For producing the file \"CloudSat_2C-SNOW-PROFILE_Antarctica_20072010_SRSinf4_1binexcluded.nc\", only the observations with a snow retrieval status lower than 4 in which snowfall is observed in at least two vertical bins have been taken into account (Palerme et al., 2018). In addition to the snowfall rate, the number of CloudSat orbits used to assess the mean snowfall rate is also available. The files also provide the snowfall rate uncertainty, which represents the expected uncertainties for individual snowfall rate retrievals (Wood et al., 2013, Palerme et al., 2014).本数据集提供两款基于CloudSat 2C-SNOW PROFILE产品R04版本生成的南极降雪气候学数据集。该数据集的时间覆盖范围为2007年至2010年，空间覆盖范围为南纬55°至82°之间的区域。文件CloudSat_2C-SNOW PROFILE_Antarctica_20072010_SRSinf4.nc中的降雪率，仅通过降雪反演状态低于4的观测数据计算得到（Wood等人，2013年；Palerme等人，2018年）。在生成文件CloudSat_2C-SNOW-PROFILE_Antarctica_20072010_SRSinf4_1binexcluded.nc时，仅纳入了降雪反演状态低于4且至少在两个垂直分箱中观测到降雪的有效观测数据（Palerme等人，2018年）。除降雪率数据外，数据集还提供了用于计算平均降雪率的CloudSat轨道数。此外，数据文件还包含降雪率不确定性数据，该数据代表单次降雪率反演结果的预期误差（Wood等人，2013年；Palerme等人，2014年）。
