How to Trust a Digital Photo: A Blockchain Based Proposal

With the ever-increasing sophistication of digital tools, it’s now possible to alter digital photographs or videos with enough sophistication that it’s often extremely difficult to tell if they’ve been tampered with. In 2018, eMarketer estimated that there will be 4.57 billion people with mobile phones, not to mention huge numbers of security cameras, laptops, etc., all with image sensors capable of taking and transmitting digital images to the Internet.

The World is Warming: What Can Data Do to Help?

This past summer, weather and climate-caused events have dominated the news and impacted the day to day lives of many. Each year, across the globe, heatwaves are getting hotter, while cold days are fewer. This summer, the United States alone surpassed nine all-time temperature records, with an additional ten records tied so far.

A Closer Look: the Impact of the CA Fires on Air Quality

It was only last December when we analyzed the pollution spike from the Thomas Fire, one of the largest wildfires in California’s history. Now, only half a year later, California and other states are combatting large wildfires once again.

ERA5 Reanalysis Data Available in S3

During the past few weeks, in conjunction with the AWS Public Dataset Program, we have been working to bring reanalysis data to AWS. Today we are excited to announce that an initial subset of ECMWF ERA5 data is now available in Amazon S3.

Fighting Fire with Forecasting

As the planet gets warmer and warmer, the frequency of uncontrollable, devastating fires is on the rise. Fueled by weather, wind, and dry underbrush, hundreds of thousands of wildfires burn millions of hectares of land every year.

Earth Observation Synergy

Over the last few years, the amount of data generated by consumer oriented sensors rose significantly. Everything from smart watches, thermostats, to cars and public transport are producing some form of numerical output.

The Oceanic Organism

My first computer background displayed a sand beach tapering off into a clear, blue body of water. While in practice this was a cheesy, often poor reflection of what the ocean actually represents, this image embodied a profound sense of relief and relaxation.

The Seasonal Forecaster’s Holy Grail

When launched back in 2004, the Climate Forecast System or CFS, drew excitement from the climate science community. Dr. Suranjana Saha, of the Environmental Modeling Center at NOAA writes, “The CFS provides important advances in operational seasonal prediction on a number of fronts. For the first time in the history of U.S. operational seasonal prediction, a dynamical modeling system has demonstrated a level of skill in forecasting U.S. surface temperature and precipitation that is comparable to the skill of the statistical methods used by the NCEP Climate Prediction Center (CPC).” The significance here, she goes on to write, is a “overall improvement in the operation of seasonal forecasts.”

Telling the Data-Driven Climate Story

Most would agree that climate change comes with some serious repercussions. The US department of defense, for example, includes it as one the greatest threats to the future of national security.

Global Oceanic Ice and Wind–New Datasets Now Available on Planet OS Datahub

This week, in response to multiple user requests, we’ve added two new datasets to the Planet OS Datahub. NCEP MMAB Global Visibility and Ice Accretion Guidance addresses sea ice accretion–the formation of ice on or near an object, usually a ship–and its relation to wind speed, freezing point of sea water, air temperature, and sea surface temperature.

Too Cold for More Wind?

Located on the coast of the Baltic Sea in the North Eastern reaches of continental Europe, Estonia has in recent years shown the world it means business. Outputting such disruptors as Skype, TransferWise, GrabCAD, Pipedrive and, you guessed it, Planet OS, Estonia is well positioned to model a smart society, and we’re not just saying that. We mean it, geographically.

The Practicalities of Harnessing Wind Potential

If you ever have the opportunity to fly over the large swath land separating Barstow from Las Vegas, I encourage you to look down at the panels winking back up at you. Similarly, if you ever get the chance to drive from California’s Central Valley to San Francisco, I encourage you to look up at the evolved version of Quijote’s fixation scattered across the foothills.

The Future Winter Olympic Cities: Who has the Best Weather Conditions?

Pyeongchang was a great Winter games host as it possesses ideal conditions for artificial snowmaking. But with global climate getting warmer, people are starting to wonder whether cities looking to make bids will be deterred, if they don’t have the ideal conditions for natural snow and artificial snowmaking.

Evolving Power Grid Operations Amid California’s Changing Climate

Our society has become increasingly concerned with its impact on the environment, but how we contend with the effects of a changing climate is a complex and altogether scary question. As we explore and understand this situation, it’s likely that any solution to combat climate change will have a larger effect on us all.

Bushfire Prevention — Data-Driven Powerline Installation and Brush Monitoring

About one month ago, Southern Australia experienced an extreme heat wave that melted pavement, boiled bats, and exacerbated the fire potential of an already dried out landscape. Rather than being an anomaly, this degree of heat wave may be closer to what, in the future, we view as the norm.

How the Climate in Melbourne Changed Over a Century

In the light of the ongoing heat wave in South Australia, we checked if the past 100 years reveal any significant changes in the local climate. For the analysis we used the Planet OS API and data from the Australian Bureau of Meteorology.

Hardware Security: Why Fixing Meltdown & Spectre Is So Tough

Hardware-based security is very difficult to break but, once broken, catastrophically difficult to fix. Software-based security is easier to break but also much easier to fix. Now what?

Will There Be Enough Snow for the Winter Olympics?

Using data from the NCEP Climate Forecast System Reanalysis (CFSR) and ERA5 datasets we investigate historical snow depth and air temperature in South Korea to assess the likelihood of favorable conditions for the Olympic athletes.

Five crucial security questions for your IoT project

2018 will be a big year for IoT. By some estimates 2.8 billion new devices will come online, enabling a variety of new scenarios that were science fiction just a decade ago. Connected medical devices, watches, home automation devices, smart cities, connected cars and industrial equipment are all changing the way we interact with each other and our environment, in both our personal and business lives.

Analyzing the Air Pollution Spike Caused by the Thomas Fire

Less than two months after the most destructive wildfire in the history of California the state is fighting yet another massive blaze in Ventura and Santa Barbara Counties. October’s fire in Northern California burned over 200,000 acres, destroyed nearly 6,000 structures, and claimed the lives of at least 42 people. The ongoing Thomas Fire north of Los Angeles has already burned across 270,000 acres and is causing hazardous air pollution in the region.
