Helping farmers manage their enterprises: weather and satellite APIs for agroservices
As farms mainly consist of crop fields, which can be hundreds of acres in size, much time and resources are demanded of farmers in obtaining an accurate picture of the overall condition of these farms.
Drying out of plants or, conversely, an excess of moisture and a rise in the number of pests: these can all take their toll on the size and quality of the harvest and demand a rapid response. There are also such problems as the danger of overusing fertilizers, which poses a threat not only in terms of extra costs but also in that it is harmful to the environment and primarily to the health of farmers themselves.
To maximize harvests, constant monitoring is required throughout the season; and it is not easy finding the time to keep up with changes for each crop, not to mention monitoring the condition of every single acre. When deciding on long-term plans, a comparative analysis has to be carried out for both the usual course of the seasonal cycle and, in particular, any crises that have arisen.
To assess the current situation and to keep track of changes compared with preceding seasons and with the condition of neighboring fields, accurate information on both the past and the present is needed as well as future forecasts that are as precise as possible.
There are currently numerous services that help with managing farms for any acreage: checking boundaries and nutrient and moisture intake, monitoring the negative effects of weather conditions and diseases, and controlling pest numbers. And this can all be done without having to visit the fields, just by using a phone or tablet screen or a PC.

Temperature and Soil Moisture. Their Interaction and Effect on Plant Growth
Crop farming covers around 40% of the globe and uses 85% of its fresh water.
Often, in countries where agriculture constitutes the principal occupation of farmers, due to drought and overpopulation, they find themselves in a constant battle to maintain everyday resources such as food and water etc. In such cases, productivity and crop prices assume critical importance. And they, in turn, depend primarily on atmospheric factors and soil conditions.

Meteorological and Climate Indices for Assessing the Effects of Weather Events on Agriculture
During the entirety of their lifecycle, crops are affected by a whole range of factors, the greatest influence being exerted by weather events. These have a significant and occasionally decisive effect on the size, quality, and timeliness of a harvest and, consequently, on its value.
There exist a large number of indices for assessing this effect, including both direct measurements and the results of calculations.
Currently, the main source of information is complex weather models based on the mathematical processing of large amounts of data collected from tens of thousands of stations around the world as well as the data received from satellites.

Satellite and meteorological monitoring of agricultural conditions
The effect of quantities and distribution of precipitation on crop cultivation.
Precipitation is agriculture’s main source of moisture. This includes both wet and dry precipitation. Their quantity is one of the key meteorological factors in agricultural productivity.
But it is not simply a case of there being too little or too much precipitation. No less important is its spatial and temporal distribution which increases or decreases potential productivity. The optimal amount of precipitation varies both for different climatic regions and for different crops at various stages of their growth.
Let’s take the year that has passed, 2017, as an example:
India received a total of 841.3 millimeters of precipitation during the monsoon season from June 1 to September 30 that year.
But this monsoon was somewhat freakish. In some parts there was surplus rain, and in others it was insufficient. This cannot but lead to differences in crop productivity in different parts of the country.

How Changes in the Sea Level Influence Transport Logistics: The Future and Now
All images used in this article were obtained by using a new technology called Cloudless, which was developed by the OpenWeatherMap company. This is a new, non-traditional approach to creating a low cloud cover of Earth using low and medium resolution satellite images. At the heart of this approach lie the principles used in processing Big Data and machine-learning algorithms.
More information about the Cloudless technology can be found here.
One of the most important physical consequences of global warming is the rise in sea level. Right now, the sea level is rising slowly enough, but, according to forecasts, this process will accelerate over time. This will affect the livelihoods of many coastal regions that will experience flooding. This means that the sea transport network may be seriously affected.
Shoreline erosion and land loss rates will be critical for planning coastal infrastructure.

Forecast Changes in Sea Levels. Melting of the Greenland Ice Sheet
Part of the Greenland ice sheet. Global composite coverage obtained between 08.01.2017 and 11.30.2017 using data from the MODIS spectroradiometer aboard KA Terra.
Most forecasts say that warming of our planet will continue and is likely to accelerate. Recent research shows that the oceans will rise from 2.5 to 6.5 feet (from 0.8 to 2 meters) by 2100, enough to submerge many cities on the US Eastern Seaboard. But long-term forecasts are not an exact science.
Historically there have been problems matching the changes observed with factors from different sources that supposedly contribute to this process.
At the moment, it has been established that changes in global sea levels are affected by three factors: melting of the polar ice caps and glaciers, thermal expansion of water due to warming of the seas and oceans, and local factors such as changes in marine currents and geological processes (land rising and subsidence) which overlap with the global trend.
Both with the polar icecaps and with the glaciers, the rise in air temperature causes increased melting of large ice cover.
For example, should the Greenland ice sheet alone melt, the sea level could rise by 7m.

The Weather and Sea Transport. Using Forecasts and Weather Maps for Effective Route Planning
It isn’t possible to affect weather conditions, but what is possible is to predict them.
Services currently available provide not only accurate up-to-date weather reports, and forecasts for different time-periods, but they also provide visual displays of various weather phenomena on weather maps, allowing a quick assessment of the overall picture. For such a weather-dependent industry as sea transportation, receiving timely accurate and visual information is particularly important.
Sea transport is one of the most tried and trusted ways of delivering cargo. Shipping lanes don’t need rebuilding or to be kept in working order. This is precisely why sea freight doesn’t cost as much as other modes of transportation.
Its main disadvantages are the long delivery time and the dependence of the vessel on weather conditions.
The most important meteorological variables which determine sailing conditions for sea vessels are the wind and those things which are dependent upon it: the condition of the water’s surface, precipitation, and temperature.
