Long‐running eddy covariance flux towers provide insights into how the terrestrial carbon cycle operates over multiple timescales. Here, we evaluated variation in net ecosystem exchange (NEE) of carbon dioxide (CO2) across the Chequamegon Ecosystem‐Atmosphere Study AmeriFlux core site cluster in the upper Great Lakes region of the USA from 1997 to...

The Malacca Strait is the importance waters for international shipping routes and more 200 cases of ship collisions in the period 1970-2015 in this strait. That is related to some a shallow depth waters with many small islands and strong current which is making this strait have a highest risk in certain seasons. The CMEMS data used to understanding...

Background: Nutrient briquette and biochar are used to reduce nitrogen loss and improve soil fertility. This study aimed to evaluate the interaction of biochar briquette with ammonium sulfate fertilizer for controlled nitrogen loss in soybean intercropping with Melaleuca cajuputi. Methods: The study was conducted in the wet season from November to...

Synthetic rainfall simulation using weather generator models is commonly used as a substitute at locations with incomplete or short rainfall data. It incorporates a method that can be developed into forecasts of future rainfall. This study was designed to modify a rainfall prediction system based on the principles of weather generator models and to...

Novel and long-term satellite data (2003–2017) are analyzed to investigate the variability of ocean surface chlorophyll-a (Chl-a) concentration off the Western Lesser Sunda Islands (WLSI) under the influence of the Indonesian Australian monsoon, the El Niño-Southern Oscillation, and the Indian Ocean Dipole (IOD). In this article, we first analyzed...

Indonesia is among the most affected regions by climate variability and change. Located between the Pacific and the Indian Ocean, Indonesia is mostly influenced by some climate variabilities, such as the monsoon, El-Nino Southern Oscillation (ENSO), and Indian Ocean Dipole (IOD). These climate variabilities affect significantly on the Indonesian ra...

Sorghum is a grain, forage, or sugar crop and it is more suitable to be cultivated on dry land or paddy fields during the dry season since it has a vegetative period of rapid and easily expandable without requiring a lot of water. Moreover, sorghum has a high productivity, with low risk of failure, low cost, and pest resistant plant and it can be u...

In the context of monsoon, TBO refers to the tendency of strong (weak) monsoon followed by weak (strong) monsoon with the transition occurred before the onset of the monsoon that involves the coupling processes between the atmosphereocean-land in the Indo-Pacific region and it has been described in a conceptual model. This study aims to identify th...

Researches on the analysis of 10-days rainfall data are very important, because related to the determination of the onset monsoon, either for wet or dry seasons. This research focused on Java Island, because Java Island as the center of agricultural production in Indonesia is one of the areas that are in need of climate information such as the star...

Benua Maritim Indonesia (BMI) berada di antara wilayah monsun Asia dan Australia. Kedua wilayah tersebut memiliki pola dua-tahunan yang disebut sebagai Tropospheric Biennial Oscillation (TBO). Selain itu, BMI juga mendapat pengaruh dari osilasi selatan yang terjadi di Samudera Pasifik yang dikenal dengan nama ENSO (El-Nino Southern Oscillation). Hu...

This presentation is a review of a paper from Roger K. Smith about morning glory phenomena.

A study of HBV hydrological model in Peusangan watershed Aceh as a preface study to the development of sustainable ecohydrological concept was done. The objective of the study was to apply and to test the HBV subtropical model into a tropical region Peusangan watershed. Peusangan watershed, situated in northern Aceh, covers an area of 2268.39 km2 a...

ANDI SYAHID MUTTAQIN. Utilization of NWP Model Outputs for Short-Range Weather Forecast (Case study: Pontianak, Pekanbaru, Semarang, Surabaya, and Palu). Supervised by AHMAD BEY and RAHMAT HIDAYAT. Numerical weather prediction (NWP) is an operational daily weather forecasting using mathematical equations by super-computer. The skill of NWP has im...
