This dataset accompanies the paper "Productivity in the Eurasian Steppe Zone and Changes in Their Carbon Sequestration" (note: the article is not published yet). The content of this dataset is described in the table below: Data Description Measurement units npp_trend_2001_2024 NPP trend in the Eurasian steppes for 2001-2024 kgC/m2/year npp_trend_2010_2019 NPP trend in the Eurasian steppes for 2010-2019 kgC/m2/year nee_trend_2010_2019 NEE trend in the Eurasian steppes for 2010-2019 gC/m2/year soilR_trend_2010_2019 Trend of soil respiration in the Eurasian steppes for 2010-2019 kgC/m2/year npp_changes_map_2001_2024 Classification of the transitions between quantile classes of NPP for 2001-2024 - npp_changes_map_2010_2019 Classification of the transitions between quantile classes of NPP for 2010-2019 - nee_changes_map_2010_2019 Classification of the transitions between quantile classes of NEE for 2010-2019 - LCtransitions_MMG_2001_2022 Dynamics of land use/cover for 2001-2022 in the Mongolian-Manchurian grassland (MMG) - LCtransitions_EEFS_2001_2022 Dynamics of land use/cover for 2001-2022 in the East European forest steppe (EEFS) - SPI_trend_2001_2024_MMG / SPI_trend_2001_2024_EEFS SPI trend for summer months for 2001-2024 in the Mongolian-Manchurian grassland / East European forest steppe - NPP_SPI_correlation_MMG / NPP_SPI_correlation_EEFS Correlation between SPI and NPP (2001-2024 period) in the Mongolian-Manchurian grassland / East European forest steppe - SPI_trend_2010_2019_MMG / SPI_trend_2010_2019_EEFS SPI trend for summer months for 2010-2019 in the Mongolian-Manchurian grassland / East European forest steppe - SR_SPI_correlation_MMG / SR_SPI_correlation_EEFS Correlation between SPI and soil respiration (2010-2019 period) in the Mongolian-Manchurian grassland / East European forest steppe - summer_temp_trend_MMG_1019 / summer_temp_trend_EEFS_1019 Trend of mean summer temperature (2m air temperature) for 2010-2019 in the Mongolian-Manchurian grassland / East European forest steppe °C/year SR_t2m_correlation_MMG / SR_t2m_correlation_EEFS Correlation between summer temperature and soil respiration (2010-2019 period) in the Mongolian-Manchurian grassland / East European forest steppe - Description of the values of the data "npp_changes_map_2001_2024", "npp_changes_map_2010_2019" and "nee_changes_map_2010_2019":1 - No changes, values ≤5%2 - No changes, values 5-95%3 - No changes, values ≥95%4 - Slight changes, ≤5% → 5-95%5 - Slight changes, 5-95% → ≤5%6 - Moderate changes, 5-95% → ≥95%7 - Moderate changes, ≥95% → 5-95%8 - Significant changes, ≤5% → ≥95%9 - Significant changes, ≥95% → ≤5%The algorithm for these classifications is explained in the article. Description of the values of the data "LCtransitions_MMG_2001_2022" and "LCtransitions_EEFS_2001_2022":Each value represents the land use/cover class, which was formed to 2022 on the site of other aggregated classes in points of land use/ cover transitions.0 - No changes (the point hasn't changed in land use/cover type)1 - Agriculture (e.g., croplands that previously were forest, wetland or other areas; same for other data values)2 - Forest 3 - Grassland4 - Wetland5 - Settlement 6 - OtherThe more detailed analysis of the land use/ cover changes is presented in the article.
