The resolution of infrared cameras is lower. These CDR data are valuable to meteorologists, climate modelers, and researchers in a wide range of applications. To do this, data from many sources are assimilated and includes both observations from a variety of sources ground based stations, ships, airplanes, radar and satellites—and forecasts … These maps enable you to view maps of monthly, seasonal and annual averages for the UK or your selected region. This is specific to a given day in 2012 for a city in England, and ideally I'd like to have 1-hour updates. Twitter Regional maps are only available for the period 1971-2000. Especially high-level clouds in the tropics have such diffusive cloud tops, leading to biases in retrieved cloud top temperature of up to 10 K. Starting in 1985, the historical weather data are available in hourly steps or daily aggregations with a spatial resolution of 30 km, whereas higher resolution data are available since 2008 for nearly every place on Earth. We are an environmental >consulting firm and are in need of an archived source for Hourly Cloud Cover >data for the years 1990, 1992, and 1996. Whereas the CRU TS precipitation data does show highs around Summer and lows around Winter. Single tile map layer images are provided three hourly from T+0 to T+36. In other words, variance in cloud cover accounts for nearly all the structure variance in UK temperature but somewhat less than half of the total temperature rise since 1956. I found your Cloud Top Pressure >map and feel that it may be of use to us. Re-analysis data is a gridded estimate of the state of the atmosphere at a certain time. Shown below are historical weather observations from the University of Reading (Berkshire, UK) climatological station. The analyses are based on 1 km grid-point data sets which are derived from station data. Our worldwide data availability and completeness are unique. The infrared satellite tries to determine temperature differences and uses that to present a cloud coverage image. The cloud cover data, however, should not be affected by this. Do you have an hourly archive of >these images for the years specified? It may seem intuitive that more clouds means more precipitation, but if you think about it precipitation literally is a loss of cloud cover so there's a fairly complex interplay which gets worked out in observed cloud cover at any given time. Scatter diagram showing the global monthly low cloud cover plotted versus the monthly global surface air temperature, since July 1983. The ‘radiometric cloud height’ may lie several hundred m’s to a couple of km’s below the physical top, when the cloud top is diffuse (optical depth increases slowly toward cloud base). Last figure update: 4 September 2011. For example, high-resolution cloud data can help develop and improve planning for solar energy usage. A map overlay showing a forecast of total cloud cover for the UK. No, we do not maintain archives of this data. More from this publisher All datasets from Met Office Related datasets. Dataset Description Spatial Information Temporal Information Access; ISCCP Cloud Data: The International Satellite Cloud Climatology Project (ISCCP) provides global cloud information at many resolutions (10 to 110 km) and time scales (3 hourly to monthly) derived from geostationary and polar orbiting satellite instruments. Note that the current site on the University's Whiteknights campus was established in 1968-1970; prior to then observations were made closer to the town centre on the London Road. Last data: December 2009. These data are fully complete and without any gaps. UK maps are available for the averaging periods 1961-1990, 1971-2000 and 1981-2010. ... Added to 2013-08-30 Access contraints no limitations I'd like to add a layer to display historical data on cloud cover in a Leaflet project I'm currently working on. Also, understanding how cloud cover changes through time and space will help further improve climate modeling.
