Jan 25, 2022 · Climate change is happening now. Evidences being seen support the fact that the change cannot simply be explained by natural variation. The most recent scientific assessments have confirmed that this warming of the climate system since the mid-20th century is most likely to be due to human activities; and thus, is due to the observed increase in greenhouse gas concentrations from human ...
Jan 26, 2022 · Reprinted with permission from FAA Aviation News I recently realized that I have been flying for over 30 years and I have been an A&P mechanic for 25 of those years. In all the time that I have spent around aircraft and the people who love them, I have rarely found pilots who understood the electrical systems of their aircraft.

A global false color composite that uses data from visible and near-infrared wavelengths and is consistent across all the satellites can be queried with the parameter As Meteosat-11 provides a high resolution scan for limited areas, we provide another composite where we integrate it to provide increased fidelity over Europe. It can be queried with the parameter Examples 1. RGB channel global satellite image:Current: https://api.meteomatics.com/2022-01-20T18Z/sat_rgb:idx/71.5,-180.0_-71.5,180.0:0.1,0.1/png 2. RGB channel high-definition satellite image of Europe:Current: https://api.meteomatics.com/2022-01-20T15Z/sat_rgb_hd:idx/60.0,-10.0_30.0,40.0:0.1,0.1/png
Infrared composites can be queried with the parameters The number indicates the wavelength in tenths of micrometers, e.g. sat_ir_039:idx corresponds to the channel with a central wavelength of 3.9 μm. Example 1. Global satellite image of 3.9 μm channel:Current: https://api.meteomatics.com/2022-01-20T00Z/sat_ir_039:K/65.0,-120.0_23.0,-50.0:1000x500/png
Over Europe, there are additional parameters available that provide more information on clouds as seen from space.
By combining data from sensors at various wavelengths, it is possible to distinguish cloud types due to their differing temperature and constituents. Such an image can be queried with the two parameters 1. sat_cloud_type:idx: if cloud-free, the index differentiates between cloud-free land (0) and sea (1) as well as snow covered land (2) and snow/ice covered sea (3). The different cloud types are explained in the table below. 2. sat_cloud_type_transparent:idx: cloud-free areas are set to -666 instead of 0, 1, 2 and 3. Also unclassified clouds (14) are set to -666. For visualization purposes, these indices are mapped onto colors according to the following legend: If you wish to query an image that is transparent wherever there are no clouds and emplaces the HRV image data wherever there are clouds, you can do so by means of the parameter Please note that since the image data stems from HRV, the clouds will be black wherever there is no sunlight, e.g. during the night. Examples 1. Type...
A clever combination of satellite images at certain wavelengths into an RGB can highlight low clouds and fog as well as distinguish them from one another. Two such RGB composite images queried by the following parameters: For the interpretation of sat_day_fog:idx images please refer to the PDF SEVIRI Dust RGB Quick Guide. As indicated by the title of the PDF, this is also helpful with tracking dust clouds. A brief guide to reading the sat_night_fog:idx images can be found in the PDF Night Microphysics RGB Quick Guide, with a more detailed presentation containing a lot of examples located here. Please note that the composite is tuned for night time and the presence of sunlight has a significant impact on both the contrast and interpretation of the colors. Examples 1.

Jan 15, 2022 · Primary focus through the long term will revolve around the Tuesday into Tuesday night time frame as a clipper is expected to dive out southwest Canada into the Upper Midwest, with a colder shot of Arctic air progged for the second half of the week. Monday through Tuesday morning will feature seasonable temperatures and dry conditions.
5 days ago · With this uncertainty, only chance PoPs are forecasted for Tuesday at this time. After the frontal passage Tuesday night, dry conditions are likely to persist for the remainder of the work week with below normal temperatures for this time of year. AVIATION /03Z SATURDAY THROUGH WEDNESDAY/.
