Autor: Ilseok Noh, Hae-Won Doh, Soo-Ock Kim, Su-Hyun Kim, Seoleun Shin, Seung-Jae Lee
Publikováno v: Atmosphere, Vol 12, Iss 7, p 846 (2021)
Spring frosts damage crops that have weakened freezing resistance after germination. We developed a machine learning (ML)-based frost-classification model and optimized it for orchard farming environments. First, logistic regression, decision tree, r

A drought index designed for field-scale water management
Autor: Jin I. Yun, Jin-Hee Kim, Soo-ock， Kim, Dae-Jun Kim, Kyo-Moon Shim
Publikováno v: Asia-Pacific Journal of Atmospheric Sciences. 51:197-203
A drought index with respect to the spatio-temporal scale was developed in response to the demand from the agricultural sector in South Korea. The new drought index was calculated based on the soil water balance between the supply and demand of water

Combined effects of wind and solar irradiance on the spatial variation of midday air temperature over a mountainous terrain
Autor: Jin-Hee Kim, Jin I. Yun, Kyo Moon Shim, Soo-ock， Kim, Dae-Jun Kim
Publikováno v: Asia-Pacific Journal of Atmospheric Sciences. 51:239-247
When the midday temperature distribution in a mountainous region was estimated using data from a nearby weather station, the correction of elevation difference based on temperature lapse caused a large error. An empirical approach reflecting the effe

Improving usage of the Korea Meteorological Administration's Digital Forecasts in Agriculture: III. Correction for Advection Effect on Determination of Daily Maximum Temperature Over Sloped Surfaces
Autor: Jin I. Yun, Soo-ock， Kim
Publikováno v: Korean Journal of Agricultural and Forest Meteorology. 16:297-303
The effect of solar irradiance has been used to estimate daily maximum temperature, which make it possible to reduce the error inherent to lapse-rate based elevation difference correction in mountainous terrain. Still, recent observations indicated t

User-specific Agrometeorological Service to Local Farming Community: A Case Study
Autor: Soo-ock， Kim, Jin-Hee Kim, Dae-Jun Kim, Jin I. Yun
Publikováno v: Korean Journal of Agricultural and Forest Meteorology. 15:320-331
The National Center for AgroMeteorology (NCAM) has designed a risk management solution for individual farms threatened by the climate change and variability. The new service produces weather risk indices tailored to the crop species and phenology by

Distribution of Midday Air Temperature and the Solar Irradiance Over Sloping Surfaces under Cloudless Condition
Autor: Jin I. Yun, Soo-ock， Kim
Publikováno v: Korean Journal of Agricultural and Forest Meteorology. 15:291-297
Automated weather stations were installed at 9 locations with, three different elevations, (i.e., 50m, 100m, and 300m a.s.l.) with different slope and aspect in a small watershed (50km 2 area). Air temperature at 1500 LST and solar radiation accumula

Improving Usage of the Korea Meteorological Administration's Digital Forecasts in Agriculture: I. Correction for Local Temperature under the Inversion Condition
Autor: Dae-Jun Kim, Jin I. Yun, Soo-ock， Kim, Jin-Hee Kim
Publikováno v: Korean Journal of Agricultural and Forest Meteorology. 15:76-84
An adequate downscaling of the official forecasts of Korea Meteorological Administration (KMA) is a prerequisite to improving the value and utility of agrometeorological information in rural areas, where complex terrain and small farms constitute maj
