Description
This dataset provides the Standardized Soil Moisture–Temperature Compound Index (SSTCI), a daily compound indicator designed to quantify compound dry–hot extremes (CDHEs) by explicitly modeling the statistical dependence between soil moisture deficits and temperature anomalies. SSTCI is produced at 0.1° spatial resolution with daily temporal resolution for the period 1961–2023 (365-day calendar; leap days removed).
Data contents
Main product
-
SSTCI: daily gridded SSTCI values stored in NetCDF format.
Variables
The NetCDF file includes:
-
SSTCI(time, lat, lon)— daily compound index (unitless; standardized) -
time— daily timestamps (365-day calendar; leap days removed) -
lat,lon— geographic coordinates (regular 0.1° grid)
Spatial and temporal coverage
-
Spatial resolution: 0.1° × 0.1° (global land grid)
-
Temporal resolution: daily
-
Time span: 1961–01–01 to 2023–12–31 (leap days removed)
Missing values
Ocean grid cells and locations without valid input data are stored as missing values (NaNs).
Code availability
The full source code used to compute SSTCI is publicly available at:

A separate repository provides the CDHE event identification workflow and event catalogue generation:
