cmip6中的降水单位一般是 k g m − 2 s − 1 kgm^{-2}s^{-1} kgm−2s−1 ,一般观测降水数据如GPCP为 m m / d a y mm/day mm/day,如何转换呢？
# 转换为mm/day
def kgm2s_to_mmday(kg_m2_s):return kg_m2_s * 86400# 转换为mm^2/day^2
def kgm2s_to_mm2day2(kg_m2_s):mm_day = kgm2s_to_mmday(kg_m2_s)return mm_day / 86400# 示例使用
kg_m2_s = 10 # 例如，某个数据为10 kg/m^2/s
mm_day = kgm2s_to_mmday(kg_m2_s)
mm2_day2 = kgm2s_to_mm2day2(kg_m2_s)print("转换为 mm/day:", mm_day)
print("转换为 mm^2/day^2:", mm2_day2)https://www.researchgate.net/post/How-do-I-convert-ERA-Interim-precipitation-estimates-from-kg-m2-s-to-mm-day
