Air temperature data for C1 chart recorder, 1952 - ongoing.

Temperature data were collected on a daily time-scale
from the C-1 climate station (3018 m) since 1952. Over time various
circumstances have led to days with missing values. These values were
estimated from redundant sensors and nearby climate stations and using
various methodolgy. Greenland 1987 was a basis for methodology however
when not possible to use this methodolgy, new methods were developed. NOTE: The LTER data portal display does not display important maintenance/log information
or other EML metadata features.
Please be sure to view the EML file (a text file that contains XML tags) which is included in
the zip archive (click on "Download zip archive")
pertaining to each dataset. The EML file name will have the following format:
knb-lter-nwt.[3 digit dataset number].[version number].xml. Most web browsers can
parse the EML so it's easier to read.

本数据集包含1952年起来自海拔3018米的C-1气候站（C-1 climate station）的逐日气温观测数据。随着观测周期延长，受多种客观因素影响，部分日期存在数据缺失值。研究人员通过冗余传感器、邻近气候站的观测数据，并结合多种方法对缺失值进行了插补估算。1987年格陵兰的相关数据集曾作为本次插补方法的参考基准，当该方法无法适用时，研究团队另行开发了适配的新方法。
