Short Summary

This study examines how drought asymmetrically amplifies the lagged and cumulative responses of vegetation productivity to soil and atmospheric droughts, finding the effect to be most pronounced for vapor pressure deficit.

Objective

• To investigate the asymmetric amplification of lagged and cumulative vegetation productivity responses to soil and atmospheric droughts.

Study Configuration

• Spatial Scale: China (0.05° spatial resolution)
• Temporal Scale: 2001–2023 (monthly temporal resolution)

Methodology and Data

• Models used: Not specified (statistical analysis of geospatial datasets)
• Data sources:
  • Gross Primary Production (GPP): GOSIF GPP dataset
  • Land cover: MODIS MCD12C1 (2012 data)
  • Climate variables (precipitation, potential evapotranspiration, soil moisture, and vapor pressure deficit): TerraClimate dataset

Main Results

• Drought asymmetrically amplifies the lagged and cumulative responses of vegetation productivity to both soil and atmospheric droughts.
• The amplification effect is stronger for vapor pressure deficit (VPD) compared to other drought indicators.

Contributions

• The research clarifies the differential impacts of soil versus atmospheric droughts on vegetation productivity, highlighting the dominant role of VPD in driving lagged and cumulative productivity declines.

Funding

• Not specified
