Introduction

Analysis of the core content of the standard

Parameters	QX/T 368-2016	WMO 1981	ASTM E490-00a
Solar constant	1366.1 W/m²±0.0425%	1367 W/m²±7 W/m²	1366.1 W/m²
Spectral range	0.1195-1000μm	0.25-25μm	0.1195-1000μm
Data source	6 satellites (1978-1998)	Ground-based observations	Multi-platform fusion data

Evolution of key technologies

This standard uses satellite observation data from absolute radiometers and spectral radiometers. Compared with the 1981 WMO standard:

Uncertainty increased from ±0.5% to ±0.0425%

Spectral resolution increased 100 times

The ultraviolet band extends to 0.1195μm

Implementation and application suggestions

Meteorological field: When used for radiation transfer model input, it is recommended to give priority to the 0.3-3μm band data in Table 1 (accounting for 97.7% of the total solar radiation)

Aerospace engineering: Thermal balance experiments should focus on:

The impact of the ultraviolet band (＜0.4μm) on material aging

The heat load of the near infrared (0.7-1.1μm) on the temperature control system

Unit conversion guide

The solar constant 1366.1 W/m² is equivalent to:

1.959 cal/(cm²·min) (thermochemical calorie)

433.4 Btu/(ft²·h)

1.956 Langley/min
