This was not being done meaning that cloud concentrations were usually too small.ī) The UM cloud concentrations are also grid box average values, and the UM provides individual cloud fractions for liquid and ice cloud in addition to the total (area) cloud fraction. This means the model concentrations should be divided by the cloud fraction before being passed to RTTOV. For IR cloud simulations RTTOV requires the cloud concentration of the cloud fraction of the layer. Issue: for observations with longitudes close to 0/360 degrees, the interpolation may not always yield the closest grid point to the observation location due to the code not checking the minimal longitudinal distance between points.Ī) IR cloud simulations using ECMWF GRIB data or NWP SAF profile datasets.Ĭ) all simulations where the first profile being simulated lies outside the domain of the model data.Ī) The ECMWF cloud liquid and ice concentrations are grid box average values. It is recommended to apply the above fix. NB This bug no longer applies: the fix above dated replaces the nearest neighbour calculation with a more accurate method. The fix above applies to all RadSim 2.x versions. This bug has been fixed: download the update for the nearest-neighbour bug above dated. Issue: the interpolation does not account for negative longitudes in the model grid with rotated poles with the result that RTTOV is run with incorrect profile data and typically reports run-time failures. Īffects: interpolation when running RadSim using model data with a rotated pole and an observation datafile when the model longitudes include negative values. Note this update fixes the bug below dated and supersedes the bug below dated. This bug has been fixed: download this updated source file to src/code/main/ and recompile RadSim. Issue: the method for determining nearest neighbours was not strictly correct, so that although it returned one of the neighbouring grid points to each observation, it didn't always return strictly the nearest. This applies to RadSim v2.1 and v2.2.įor RadSim v2.0 use this source file instead.Īffects: nearest neighbour interpolation used when ingesting DWD ICON fields with an observation datafile (v2.2 only). Issue: the qcinfo(:) array was being written instead of the qcrttov(:) array to the qcrttov dataset in the output netCDF file. Please contact the Help desk if you require a fix for RadSim v2.0.Īffects: output of qcrttov quality flags. Issue: the interpolation code does not correctly handle observations that lie exactly on the latitude boundary of the model domain. A separate version is also available for older operating system versions.Affects: simulations using regular lat/lon model grids for non-global domains where observations lie on the latitude boundary. You can download the TypeStatus 2 tweak from Cydia, where it is available for free. The icon appears as is shown in the image below. Another cool feature of this tweak allows users to configure the tweak to only show a small icon in the status bar to indicate the typing and read reports or take the whole status bar, as shown in the screenshot above. This functionality allows users to know whether someone has read their message or has started typing a reply, no matter which part of the operating system they are using currently.įrom Settings users can choose the display duration for the TypeStatus to appear, turn off alerts for typing or reading, turn off the tweak when the Messages app is opened etc. For those of you who are not familiar with TypeStatus 2, this tweak puts the read and typing reports of iMessage in the status bar of the device. Now TypeStatus 2 has been updated in Cydia, which brings the same feature to iOS 9 powered devices. We are sure many of you would already be familiar with the TypeStatus 2 tweak, which has been around for years and has been covered by us at several occasions.
