The minimum value of GPP percentiles during the drought period is considered the response intensity of GPP to flash and slow droughts. Response time is the duration of GPP from 8 days before flash droughts to the timing of the occurrence of the minimum GPP value. The loss in GPP percentiles is defined as the decrease in GPP from 8 days before the onset of droughts to the timing of the minimum values during the drought. Declining rates are calculated as the slopes between the decline in GPP percentiles and response time to represent the resistance of vegetation growth to droughts.
