All Weather And Climate Data Are Not Created Equal!
You can't afford errors in weather data to impact your decisions and your bottom line.
Even small errors in weather data can accumulate over time and distort your view of
the weather and the impact on your business. There are numerous sources of weather data
these days, including many that are free. Do you really want to trust a free source? The
reality is that you can't even trust "official" data sources as their data is also not
clean. At AWIS, we are all about cleaning up the data. Clean weather data allows for:
AWIS Weather And Climate Data Are CleanWeather sensors break, automated measurements can drift, data may be garbled in transmission, and human errors abound. Identifying errors and cleaning up weather and climate data takes time, experience and resources. Our quality control is rigorous and complete. AWIS meteorologists quality control yesterday's data today. Knowing the current weather situation and using all available surface weather observations, weather radar, and satellite data, we can more accurately find and correct data errors.
AWIS Weather And Climate Data Are Consistently MeasuredInconsistencies in measuring equipment, sampling frequencies and the time of sampling are common problems among different weather networks. Equipment placement can have a huge impact on the data. Some networks place equipment on rooftops, a fine way to introduce warm trends. Sensors drift and require maintenance. Some networks are virtually never maintained. All AWIS weather observations are from observation systems established and maintained by the National Weather Service and other Federal and State agencies. We don't put data in our database without assurances that it meets the latest scientific standards.
Available Data LocationsWe closely monitor the reliability of weather reporting sites worldwide. Each month we update our statistics and use these reliability statistics to match the best weather reporting locations to your needs. We supply detailed maps and station listings with latitude/longitude, elevation, etc when quoting our services.
AWIS Delivers Data In Your Format And On Your Time TableYesterday's weather data are available today with complete quality control. Raw weather data are available immediately. Most data are delivered electronically via FTP, private web pages, or e-mail. Historical weather data and climate normals can also be delivered on CDs or other storage devices. Both custom and standard formats are available. Our weather and climate data is ready to ingest, with minimal work for the client. AWIS weather and climate data is spreadsheet and database ready. We can meet any format specifications.
We Can Calculate Any Weather-Based Variables
Climate Data NormalsWe maintain an extensive global database of climate data, often referred to as "normals". By convention, normals are computed for 30 year periods ending each decade. The latest normals are for 1981-2010. Normals are essential for making comparisons to current conditions and for developing weather-based models. Daily and monthly normals are available for temperature and precipitation. We have also calculated long-term averages of selected other parameters.
Historical Weather DataData are available for the period of record for thousands of locations around the world. Data starts for many locations in the 1940s with some locations having data back even further. Our database includes hourly as well as daily data. Our reliability statistics allow us to provide you with the best available data. We also have historical data that has not been archived by the government.
On-going Current Weather DataOur computers are constantly processing satellite and internet feeds to maintain a database of global weather conditions. We can supply the latest hour, the past 24 hours, or any desired time frame. In addition to a live feed of data, we can supply next day cleansed data after the data passes our rigorous quality control. Our feed contains data that is not being archived by the government.
Source of Our Weather and Climate DataOur Climate Data Normals are derived from official sources where possible. In the US, our normals are based on the official data from the National Climate Data Center. We have computed our own normals for many foreign locations where official normals are unavailable. Our Historical Weather Data is a combination of data from official sources and data that we have collected, cleaned, and added to our database. Our historical weather database is often more complete than the offical database due to our quality control. On-going Weather Data are extracted from satellite and internet broadcasts received directly from the National Weather Service and other reliable sources. The data are from observation systems established and maintained by the appropriate Federal or state agency. We don't use data from unauthenticated and unreliable sources. However, for our consulting work we dig even deeper and utilize data from all available sources.
AWIS Provides More Than Weather And Climate DataWe consult on weather-related projects. AWIS's team of skilled meteorologists works hard to find new, creative, and efficient ways to address even the most challenging problems. AWIS provides more than numbers. Input from AWIS meteorologists can have a significant impact on your project. We've worked with hundreds of companies and organizations. Numbers may not describe what you want and some measures have little meaning. Our experience can work for you too.
