Monthly RACMO2.4p1 data for Greenland (11 km) and Antarctica (27 km) for SMB, SEB, near-surface temperature and wind speed (2006-2015)

Version 2: Updated missing months in the Antarctic data set. Monthly-accumulated (named monthlyS) and monthly-averaged (named monthlyA) data for RACMO2.4p1 for Greenland (GRN) and Antarctica (ANT) on a 11 km and 27 km horizontal resolution grid, respectively, are presented in this data set and are available for 2006 until 2015. The data include the surface mass balance (SMB), snow melt (mltgl), refreezing (rfrzgl), precipitation (pr), runoff (totrunoff), drifting snow erosion (sndiv), sublimation (sublgl) and sublimation due to blowing snow (sublsd), all in kg m-2 mo-1. For the surface energy balance (SEB): the downward shortwave radiation (rsds), shortwave upward radiation (rsus), downward longwave radiation (rlds), upward longwave radiation (rlus), sensible heat flux (hfss) and latent heat flux (hfls) are available. The SEB components are in J m-2. To convert to W m-2, divide by the amount of seconds in a month. In addition, the near-surface temperature (tas), in K, and near-surface wind speed (sfcwind), in m s-1, are included. This data set does not represent new surface mass balance and climate products for Greenland and Antarctica. For Antarctica, a surface mass balance and climate product with RACMO2.4p1 can be found here: https://doi.org/10.5281/zenodo.14217231. Products for Greenland will follow in later publications, where RACMO2.4 simulations are presented covering the full historical time period of ERA5 with higher horizontal resolution.版本2：更新了南极数据集中缺失的月份数据。 本数据集提供格陵兰（Greenland, GRN）与南极（Antarctica, ANT）区域基于RACMO2.4p1模式的月累加（命名为monthlyS）与月平均（命名为monthlyA）数据，二者分别采用11 km与27 km的水平分辨率网格，时间覆盖2006年至2015年。数据包含地表质量平衡（surface mass balance, SMB）、融雪量（snow melt, mltgl）、雪层再冻结量（refreezing, rfrzgl）、降水量（precipitation, pr）、径流量（runoff, totrunoff）、吹雪侵蚀量（drifting snow erosion, sndiv）、升华量（sublimation, sublgl）以及风吹雪引发的升华量（sublimation due to blowing snow, sublsd），所有变量单位均为kg·m⁻²·月⁻¹。 针对地表能量平衡（surface energy balance, SEB），本数据集提供向下短波辐射（downward shortwave radiation, rsds）、向上短波辐射（shortwave upward radiation, rsus）、向下长波辐射（downward longwave radiation, rlds）、向上长波辐射（upward longwave radiation, rlus）、感热通量（sensible heat flux, hfss）与潜热通量（latent heat flux, hfls）。地表能量平衡各分量的单位为J·m⁻²。若需转换为瓦每平方米（W·m⁻²），需将数值除以当月总秒数。此外，数据集还包含近地表气温（near-surface temperature, tas，单位为开尔文K）与近地表风速（near-surface wind speed, sfcwind，单位为m·s⁻¹）。 本数据集并非格陵兰与南极地区的全新地表质量平衡及气候产品。针对南极地区，可通过以下链接获取基于RACMO2.4p1模式的地表质量平衡与气候产品：https://doi.org/10.5281/zenodo.14217231。格陵兰地区的相关产品将在后续研究中发布，届时将展示覆盖ERA5完整历史时段、具备更高水平分辨率的RACMO2.4模式模拟结果。
