地表温度是天气和气候的一个关键方面，但这个术语可能指的是不同的量，这些量起着相互关联的作用，并通过不同的方式进行观测。在2012年6月的一次社区活动中，地球温度网络汇集了来自五大洲的55名研究人员，以改善侧重于特定领域地表温度的科学界之间的互动，利用不同观测系统的优势，更好地满足不同社区的需求。研讨会确定了在满足科学和社会对地表温度理解和信息的要求方面取得进展的关键需求，这些需求在本社区文件中提出。需要从“整个地球”的角度，采取更加综合、协作的办法来观测和了解地球各种表面温度。有必要了解不同表面温度之间的关系，目前还不够，并进行大规模的系统相互比较。数据集需要更容易为广大用户获取和利用，以易于理解的术语说明差异和互补性，并提供现实和一致的不确定性信息。还建议采取步骤，整理和提供目前无法获得的数据，开发新的观测系统，并建设能力，以加快在地表温度数据集的准确性和可用性方面取得进展。
Surface temperature is a key aspect of weather and climate, but the term may refer to different quantities that play interconnected roles and are observed by different means. In a community-based activity in June 2012, the EarthTemp Network brought together 55 researchers from five continents to improve the interaction between scientific communities who focus on surface temperature in particular domains, to exploit the strengths of different observing systems and to better meet the needs of different communities. The workshop identified key needs for progress towards meeting scientific and societal requirements for surface temperature understanding and information, which are presented in this community paper. A "whole-Earth" perspective is required with more integrated, collaborative approaches to observing and understanding Earth's various surface temperatures. It is necessary to build understanding of the relationships between different surface temperatures, where presently inadequate, and undertake large-scale systematic intercomparisons. Datasets need to be easier to obtain and exploit for a wide constituency of users, with the differences and complementarities communicated in readily understood terms, and realistic and consistent uncertainty information provided. Steps were also recommended to curate and make available data that are presently inaccessible, develop new observing systems and build capacities to accelerate progress in the accuracy and usability of surface temperature datasets.
