Homogenization of Daily Temperature Data

Journal of Climate, 2017
Abstract This paper develops a method for homogenizing daily temperature series. While daily temperatures are statistically more complex than annual or monthly temperatures, techniques and computational methods have been accumulating that can now model and analyze all salient statistical characteristics of daily temperature series.

A temperature calculation model: The case of minimum daily temperature

Atmospheric Environment. Part A. General Topics, 1993
Abstract In the present work a model based on the linear relationship between variations in the relative humidity of the air and those of temperature is applied to calculate minimum daily temperatures as a function of the maximum humidity value and the value measured in a thermometer screen at 1800 UTC of the previous day.

Daily temperature extremes as an indicator of high temperature stress

Australian Journal of Soil Research, 1991
Theory outlining a general relationship between stress experienced by an organism exposed to supra-optimal temperatures and daily temperature extremes is discussed. It is shown that useful nomograms relating Tmax, Tmin, Tcritical, and high temperature stress can be developed and that these nomograms are not particularly sensitive to changes in ...

Temperature Effects on the Winter Daily Electric Load

Journal of Applied Meteorology, 1982
Abstract Here we describe the relationship between average daily temperature and winter-daily electric load, as ascertained on the largest electric district in Italy. In particular, it is shown that a sudden 6°C temperature decrease (not a rare event) raises the load by ∼5%. Several aspects of users' behavior before temperature changes are also pointed

Daily temperature variations on Mars

Journal of Geophysical Research: Solid Earth, 1982
The Viking infrared thermal mapper (IRTM) has measured the infrared brightness temperature of Mars for more than a full Martian year. The daily variation of the 20‐μm brightness temperature can be predicted to within ±5 K for most of the Martian surface during any season if the radiometric albedo and the thermal inertia of the model are allowed to ...

The relation between daily activities and scrotal temperature

Reproductive Toxicology, 2002
Normal sperm production depends on a testicular temperature below body temperature, but the thermogenic effects of daily life activities are not well known. We described the association between scrotal temperature and daily activities in 101 males using a non-invasive method for measuring scrotal temperature.

XI.—The Daily Temperature Curve

Proceedings of the Royal Society of Edinburgh, 1921
(1) Outline of Investigation.—During the last half-century the temperature of the air has been recorded by thermographs at a number of places, and the registered graphs have been measured and mean daily temperature curves have been calculated from them for each month of the year. The amount of labour entailed in these operations is enormous, and it may

DAILY TEMPERATURE OPTIMISATION IN GREENHOUSE BY REINFORCEMENT LEARNING

IFAC Proceedings Volumes, 2005
Abstract The goal of this study is to show the usefulness of reinforcement learning (RL) to solve a common greenhouse climate optimisation problem. The problem is to minimise the daily heating cost while achieving simultaneously two agronomic goals, namely maintaining a good crop growth and an appropriate development rate.

Effect of suprachiasmatic ablation on the daily temperature rhythm

Neuroscience Letters, 1977
Abstract To evaluate the role of the suprachiasmatic nuclei (SCN) in maintenance of body temperature, the rectal temperature of 5 SCN ablated and 8 intact female rats were measured every 4 h over a 48-h period (80 days postsurgery). Intact as well as SCN ablated rats showed significant 24-h fluctuations in body temperature.

Influence of Lunar Phase on Daily Global Temperatures

Science, 1995
A newly available data set of daily satellite-derived, lower-tropospheric global temperature anomalies provides an opportunity to assess the influence of lunar phase on planetary temperature. These results reveal a statistically significant 0.02 K modulation between new moon and full moon, with the warmest daily global temperatures over a synodic month
