A range of different technologies has been developed over the past 40 years to observe profiles of temperature and humidity fro m the ground.  These methods include passive techniques\, such as single- and multi-channel microwave radiometers (MWRs) and infrared spectrometers (IRS)\, and active approaches\, such as Raman lidars (RLID)\, differential absorption lidars (DIALs)\, and radio acoustic sounding systems (RASS). A ll of these techniques have strengths and weaknesses\, and it can be chall enging to evaluate the relative differences in their information content i n a consistent way. Furthermore\, this leads to questions on how to combin e observations from multiple instruments synergistically. Additionally\, t he profiles derived from many remote sensors have correlated errors betwee n different height levels\, and thus the covariance of the profile needs t o be understood if the profiles are to be properly assimilated into a weat her forecast model.\nWHAT IS TROPOE:\nTo address these questions\, we have developed the TROPoe retrieval software package. TROPoe is a 1-dimensiona l variational algorithm\, based upon optimal estimation\, that incorporate s forward models for all of these instruments to allow an iterative soluti on to be determined. A climatology\, usually of historical radiosondes lau nched near the instrumented site\, is used to provide a constraint to the retrieved solution. Uncertainties from the observations\, the sensitivity of the forward models\, and the uncertainty in the prior are all propagate d to provide a full error covariance matrix for each retrieved thermodynam ic profile. Retrievals using single instrument configurations (e.g.\, MWR- only\, IRS-only\, DIAL-only) as well as multi-instrument retrievals (e.g.\ , MWR+IRS\, MWR+DIAL\, IRS+RLID\, MWR+IRS+DIAL) can be performed. When the same retrieval framework and prior dataset is used\, the uncertainties an d information content for each instrument complement can be directly compa red.\nTHE TRAINING:\nThe TROPoe software has been packaged into a Docker c ontainer\, which facilitates the use of the software by a wide range of us ers. Next to an introduction to the retrieval theory\, this workshop will provide a hands-on training to users on how to apply TROPoe to provide con sistent retrievals from the ground-based remote sensing observations\, inc luding how to combine data from multiple different instruments into the re trieval. The workshop will also focus on understanding the generated outpu t\, including the uncertainty and information content output produced by T ROPoe. The goal is that the user can “take home” the retrieval and apply i t to their observations “at home”. Lastly\, the workshop will discuss how to assimilate these retrieved profiles\, regardless of the actual instrume nt datasets used in the analysis.\nAPPLICATION: \nPROBE scientists and FES STVaL Early Career Investigators are invited to apply for this 2\,5-day wo rkshop in Cologne until March 4th. On March 8 we will inform you about the success of your application and finally communicate to you if the worksho p will take place as planned as an in-person meeting or if we need to use an on-line format due to the COVID-19 situation. Please note: After a succ essful application\, we require valid proof of full COVID-19 vaccination o r timely recovery.\nIf you want to apply\, click here.\nORGANIZATIONAL ASP ECTS:\n\nTime plan:\n\nThe training school will take place twice:\n- from March 28 (7 UTC) to March 30 (10 UTC)\, PROBE participants\n- from March 3 0 (12 UTC) to April 1 (16 UTC)\, FESSTVaL participants.\nEach workshop eve nt will be open for 10 participants. \nPlease book your travel only in cas e of a positive notification on March 8. At that point\, we will provide t ravel advice and hotel booking assistance. Up to 10 scientists from PROBE will be awarded a travel grant through a commission. More information will be available on March 8. ECIs from FESSTVaL can apply for travel reimburs ement from their project funding using funds originally designated for the FESSTVaL summer school. The workshop as such is free of charge.\n\nTraini ng School Instructor: David D.
