Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" drafted.

Introduction

Land surface temperature is a key parameter of terrestrial surface system processes at regional and global scales, which characterize the interaction between the surface and the atmosphere and and the comprehensive result of energy exchange between the atmosphere and land, is an important parameter in the process of obtaining information on the temporal and spatial changes of the surface energy balance.

Numerical forecasting, global circulation models, and regional climate models are widely used in research fields. Obtaining an accurate surface temperature not only helps in evaluating It can estimate the surface energy and water balance, thermal inertia and soil moisture, and help to grasp the long-term trend of global surface temperature.

Satellite remote sensing technology has the characteristics of fast speed, high temporal and spatial resolution, and is suitable for long-term continuous observation of large areas.

The most direct and economical means of obtaining surface temperature at a regional or global scale. Several sets of satellite remote sensing technology-based geography have been released at home and abroad.

Surface temperature products, but due to the difference in the degree of definition and application level of surface temperature products, the surface temperature products produced by different institutions or organizations Consistency between products is poor. Differences in the composition, grading and labelling of surface temperature products make it difficult for different researchers to use There is a certain blindness in the application process, which generates additional costs, increases the application complexity, and hinders the orderly development and wide application of surface temperature products. Wide application.

This document is based on the development of surface temperature products and the needs and trends of their industrialization.

Make uniform technical regulations on the classification, naming rules, product composition, technical requirements and product inspection of surface temperature products, so as to establish a scientific, cooperative and It can improve the application level of surface temperature products, and provide users with the structure and content of the required products, which is convenient for users.

For the access and correct use of surface temperature products, the industrialization development of my country's surface temperature products will be promoted.
